Korean ( 한국어 / 조선말 , see ) is the official language of the Republic of Korea and Democratic People's Republic of Korea , with different official forms used in each nation-state; it is also one of the two official languages in the Yanbian Korean Autonomous Prefecture and Changbai Korean Autonomous County of the People's Republic of China . Approximately, 80 million people speak Korean worldwide. 
Korean has a few extinct relatives, which together with Korean itself form the Koreanic language family . Despite this, historical linguists classify Korean as a language isolate .  The idea that Korean belongs to a putative Altaic language family has been generally discredited. There is still debate on whether Korean and Japanese are related languages.  The Korean language is agglutinative in its morphology and SOV in its syntax .
Modern Korean descends from Middle Korean , which in turn descends from Old Korean , which descends from the language spoken in Prehistoric Korea (labeled Proto-Korean), whose nature is debated, in part because Korean genetic origins are controversial. A relation of Korean (together with its extinct relatives which form the Koreanic family ) with Japonic languages has been proposed by linguists like William George Aston and Samuel Martin . Roy Andrew Miller and others suggested or supported the inclusion of Koreanic and Japonic languages in the purported Altaic family (a macro-family that would comprise Tungusic , Mongolian and Turkic families), now not accepted by most specialists.
Chinese characters arrived in Korea together with Buddhism during the pre- Three Kingdoms period and remained as the sole script for writing Korean through over a millennium (Chinese script adapted for Korean is known as hanja ) along with the phonetic scripts that were later invented. Only privileged elites were educated for fluently read and write them, though, as most of the population was illiterate. In the 15th century, King Sejong the Great felt that the hanja were not adequate to write Korean and this was the cause of its very restricted use, so (with a likely help of the Hall of Worthies ) he developed an alphabetic featural writing system known today as hangul , which was designed to either aid in reading hanja or replace them. Introduced in the document hunminjeongeum , it quickly became popular and increased literacy in Korea, but it was only after the end of World War II that it was definitely widespread and made official in both North and South Koreas. Today, the hanja are largely unused in everyday life, but in South Korea they experience revivals on artistic works and are important in historic and/or linguistic studies of Korean.
The Korean names for the language are based on the names for Korea used in North and South Korea.
In South Korea, the Korean language is referred to by many names including hanguk-eo "Korean language"), hanguk-mal , "Korean speech") and uri-mal , "our language"). In " hanguk-eo " and " hanguk-mal ", the first part of the word, " hanguk ", refers to the Korean nation while " -eo " and " -mal " mean "language" and "speech", respectively. Korean is also referred to as guk-eo , literally "national language"). This name is based on the same Chinese characters meaning "nation" + "language") that are also used in Taiwan and Japan to refer to their respective national languages.
In North Korea and Yanbian Korean Autonomous Prefecture in China , the language is most often called Chosŏn-mal', or more formally, Chosŏn-ŏ ( The English word "Korean" is derived from Goryeo , which is thought to be the first dynasty known to Western countries. Korean people in the former USSR , who refer to themselves as Koryo-saram also Goryeo In"; literally, " Goryeo person(s)"]) call the language Koryo-mar
In mainland China , following the establishment of diplomatic relations with South Korea in 1992, the term Cháoxiǎnyǔ or the short form: Cháoyǔ has normally been used to refer to the standard language of North Korea and Yanbian , whereas Hánguóyǔ or the short form: Hányǔ is used to refer to the standard language of South Korea.
Some older English sources also use the spelling "Corea" to refer to the country, and its inflected form for the language and people, "Korea" becoming more popular in the late 1800s according to Google's NGram English corpus as of 2015. 
The majority of historical linguists classify Korean as a language isolate. There are still a small number who think that Korean might be related to the putative Altaic language grouping, but linguists agree today that typological resemblances cannot be used to prove genetic relatedness of languages, as these features are typologically connected and easily borrowed from one language to the other. Such factors of typological divergence as Middle Mongolian's exhibition of gender agreement can be used to argue that a genetic relationship is unlikely.
The hypothesis that Korean might be related to Japanese has had some supporters due to some overlap in vocabulary and similar grammatical features that have been elaborated upon by such researchers as Samuel E. Martin and Roy Andrew Miller . Sergei Anatolyevich Starostin (1991) found about 25% of potential cognates in the Japanese–Korean 100-word Swadesh list .  Some linguists concerned with the issue, for example Alexander Vovin , have argued that the indicated similarities between Japanese and Korean are not due to any genetic relationship, but rather to a sprachbund effect and heavy borrowing, especially from ancient Korean into Western Old Japanese. A good example might be Middle Korean sàm and Japanese asa , meaning "hemp". This word seems to be a cognate, but although it is well attested in Western Old Japanese and Northern Ryūkyū, in Eastern Old Japanese it only occurs in compounds, and it is only present in three subdialects of the South-Ryūkyūan dialect group. Also, the doublet wo meaning "hemp" is attested in Western Old Japanese and Southern Ryūkyū. It is thus plausible to assume a borrowed term. (See Classification of Japonic languages for further details on a possible relationship.)
Among ancient languages, various closer relatives of Korean have been proposed, constituting a possible small Koreanic language family. Some classify the language of Jeju Island as a distinct modern Koreanic language.
Geographic distribution and international spread
Korean is spoken by the Korean people in North Korea and South Korea and by the Korean diaspora in many countries including the People's Republic of China , the United States , Japan , and Russia . Korean-speaking minorities exist in these states, but because of cultural assimilation into host countries, not all ethnic Koreans may speak it with native fluency.
Korean is the official language of South Korea and North Korea. It is also one of the two official languages of the Yanbian Korean Autonomous Prefecture in China.
In South Korea, the regulatory body for Korean is the Seoul -based National Institute of the Korean Language , which was created by presidential decree on January 23, 1991. In North Korea, the regulatory body is the Language Institute of the Academy of Social Sciences ( 사회과학원 어학연구소; 社會科學院語學研究所 , Sahoe Kwahagwon Ŏhak Yŏnguso ).
King Sejong Institute
The King Sejong Institute is a central public institution supporting the which is the overseas educational institution of the Korean language and Korean cultures. It was established based on Article 9, Section 2 of the [Framework Act on the National Language] in order to do coordination management of the government's propagation project of the Korean language and Korean cultures.
- Increase in the demand for the Korean language education
- Rapid increase in the Korean language education thanks to the spread of Hanryu, Increase in international marriage, expansion of Korean enterprises' making inroads into overseas markets, and enforcement of employment license system
- Necessity of the National Brand representing the educational institution of the Korean language
- Awareness of necessity of specialized brand cultivation which can do general support of overseas Korean language education based on the successful strategic propagation project of their own language
TOPIK KOREA Institute
is a lifelong educational center affiliated with a variety of Korean universities in Seoul, South Korea, whose aim is to promote Korean language and culture, support local Korean teaching internationally, and facilitate cultural exchanges.
The TOPIK KOREA Institute is sometimes compared to language and culture promotion organizations such as King Sejong Institute. Unlike the organization, however, TOPIK KOREA Institutes operate within established universities and colleges around the world, providing educational materials.
Korean has numerous small local dialects (called mal ( 말 ) [literally "speech"], saturi ( 사투리 ), or bang'eon ( 방언 ) in Korean). The standard language ( pyojuneo or pyojunmal ) of both South Korea and North Korea is based on the dialect of the area around Seoul, though the northern standard has been influenced by the dialect of P'yŏngyang . All dialects of Korean are similar to each other and at least partially mutually intelligible , though the dialect of Jeju Island is divergent enough to be sometimes classified as a separate language.  One of the more salient differences between dialects is the use of tone: speakers of Seoul dialect make use of vowel length, whereas speakers of the Gyeongsang dialect maintain the pitch accent of Middle Korean. Some dialects are conservative, maintaining Middle Korean sounds (such as z, β, ə ) which have been lost from the standard language, whereas others are highly innovative.
There is substantial evidence for a history of extensive dialect levelling , or even convergent evolution or intermixture of two or more originally distinct linguistic stocks, within the Korean language and its dialects. Many Korean dialects have basic vocabulary that is etymologically distinct from vocabulary of identical meaning in Standard Korean or other dialects, such as South Jeolla dialect /kur/ vs. Standard Korean 입 /ip/ "mouth" or Gyeongsang dialect /t͡ɕʌŋ.ɡu.d͡ʑi/ vs. Standard Korean /puːt͡ɕʰu/ " garlic chives ". This suggests that the Korean Peninsula may have at one time been much more linguistically diverse than it is at present. See also the Buyeo languages hypothesis .
Nonetheless, the separation of the two Korean nations has resulted in increasing differences among the dialects that have emerged over time. Since the allies of the newly founded nations split the Korean peninsula in half after 1945, the newly formed Korean nations have since borrowed vocabulary extensively from their respective allies. As the Soviet Union helped industrialize North Korea and establish it as a communist state, the North Koreans would therefore borrow a number of Russian terms. Likewise, since the United States helped South Korea extensively to develop militarily, economically, and politically, South Koreans would therefore borrow extensively from English. The differences among northern and southern dialects have become so significant that many North Korean defectors reportedly have had great difficulty communicating with South Koreans after having initially settled into South Korea. In response to the diverging vocabularies, an app called Univoca was designed to help North Korean defectors learn South Korean terms by translating them into North Korean ones.  More info can be found on the page North-South differences in the Korean language .
Aside from the standard language, there are few clear boundaries between Korean dialects, and they are typically partially grouped according to the regions of Korea .
|Standard language||Locations of use|
|Seoul||Seoul ( 서울 ); very similar to Incheon ( 인천/仁川 ) and most of Gyeonggi ( 경기/京畿 ), west of Gangwon-do (Yeongseo region)|
|Munhwaŏ||Northern standard. Based on P'yŏngan dialect .|
|Regional dialects||Locations of use|
|Hamgyŏng (Northeastern)||Rasŏn , most of Hamgyŏng region, northeast P'yŏngan , Ryanggang (North Korea), Jilin (China)|
|P'yŏngan (northwestern)||P'yŏngan region, P'yŏngyang , Chagang , Hwanghae , northern North Hamgyŏng (North Korea), Liaoning (China)|
|Central||Seoul , Incheon , Gyeonggi , Daejeon , Chungcheong (South Korea), Yeongseo ( Gangwon-do (South Korea) / Kangwŏn (North Korea) west of the Taebaek Mountains )|
|Yeongdong (East coast)||Yeongdong region ( Gangwon-do (South Korea) / Kangwŏn (North Korea) east of the Taebaek Mountains )|
|Gyeongsang (Southeastern)||Busan , Daegu , Ulsan , Gyeongsang region (South Korea)|
|Jeolla (Southwestern)||Gwangju , Jeolla region (South Korea)|
|Jeju||Jeju Island/Province (South Korea)|
|Bilabial||Alveolar|| Post- |
|Nasal||ㅁ /m/||ㄴ /n/||ㅇ /ŋ/|
| Plosive |
|plain||ㅂ /p/ or /b/||ㄷ /t/ or /d/||ㅈ /t͡ɕ/||ㄱ /k/ or /g/|
|tense||ㅃ /p͈/||ㄸ /t͈/||ㅉ /t͡ɕ͈/||ㄲ /k͈/|
|aspirated||ㅍ /pʰ/||ㅌ /tʰ/||ㅊ /t͡ɕʰ/||ㅋ /kʰ/|
|Fricative||plain||ㅅ /sʰ/||ㅎ /h/|
|Approximant||/w/ 1||ㄹ /l/||/j/ 1|
1 The semivowels /w/ and /j/ are represented in Korean writing by modifications to vowel symbols (see below).
The IPA symbol ⟨ ◌͈ ⟩ (a subscript double straight quotation mark, shown here with a placeholder circle) is used to denote the tensed consonants /p͈/, /t͈/, /k͈/, /t͡ɕ͈/, /s͈/ . Its official use in the Extensions to the IPA is for 'strong' articulation, but is used in the literature for faucalized voice . The Korean consonants also have elements of stiff voice , but it is not yet known how typical this is of faucalized consonants. They are produced with a partially constricted glottis and additional subglottal pressure in addition to tense vocal tract walls, laryngeal lowering, or other expansion of the larynx.
|Monophthongs||/i/ ㅣ , /e/ ㅔ , /ɛ/ ㅐ , /a/ ㅏ , /o/ ㅗ , /u/ ㅜ , /ə/ ㅓ , /ɯ/ ㅡ , /ø/ ㅚ|
| Vowels preceded by intermediaries, |
|/je/ ㅖ , /jɛ/ ㅒ , /ja/ ㅑ , /wi/ ㅟ , /we/ ㅞ , /wɛ/ ㅙ , /wa/ ㅘ , /ɰi/ ㅢ , /jo/ ㅛ , /ju/ ㅠ , /jə/ ㅕ , /wə/ ㅝ|
ㅏ is closer to a near-open central vowel ( [ɐ] ), though ⟨a⟩ is still used for tradition.
/s/ is aspirated [sʰ] and becomes an alveolo-palatal [ɕʰ] before [j] or [i] for most speakers (but see North–South differences in the Korean language ). This occurs with the tense fricative and all the affricates as well. At the end of a syllable, /s/ changes to /t/ (example: beoseot ( 버섯 ) 'mushroom').
/p, t, t͡ɕ, k/ become voiced [b, d, d͡ʑ, ɡ] between voiced sounds.
/m, n/ frequently denasalize to [b, d] at the beginnings of words.
/l/ becomes alveolar flap [ɾ] between vowels, and [l] or [ɭ] at the end of a syllable or next to another /l/ . Note that a written syllable-final ' ㄹ ', when followed by a vowel or a glide ( i.e. , when the next character starts with ' ㅇ '), migrates to the next syllable and thus becomes [ɾ] .
Traditionally, /l/ was disallowed at the beginning of a word. It disappeared before [j] , and otherwise became /n/ . However, the inflow of western loanwords changed the trend, and now word-initial /l/ (mostly from English loanwords) are pronounced as a free variation of either [ɾ] or [l] . The traditional prohibition of word-initial /l/ became a morphological rule called "initial law" ( 두음법칙 ) in South Korea, which pertains to Sino-Korean vocabulary. Such words retain their word-initial /l/ in North Korea.
Plosive stops /p, t, k/ become nasal stops [m, n, ŋ] before nasal stops.
Hangul spelling does not reflect these assimilatory pronunciation rules, but rather maintains the underlying, partly historical morphology . Given this, it is sometimes hard to tell which actual phonemes are present in a certain word.
One difference between the pronunciation standards of North and South Korea is the treatment of initial [ɾ] , and initial [n] . For example,
- "labor" – north: r odong ( 로동 ), south: n odong ( 노동 )
- "history" – north: ry ŏksa ( 력사 ), south: y eoksa ( 역사 )
- "female" – north: ny ŏja ( 녀자 ), south: y eoja ( 여자 )
Grammatical morphemes may change shape depending on the preceding sounds. Examples include -eun/-neun ( -은/-는 ) and -i/-ga ( -이/-가 ). Sometimes sounds may be inserted instead. Examples include -eul/-reul ( -을/-를 ), -euro/-ro ( -으로/-로 ), -eseo/-seo ( -에서/-서 ), -ideunji/-deunji ( -이든지/-든지 ) and -iya/-ya ( -이야/-야 ). However, -euro/-ro is somewhat irregular, since it will behave differently after a rieul consonant.
|After a consonant||After a ㄹ (rieul)||After a vowel|
|-ui ( -의 )|
|-eun ( -은 )||-neun ( -는 )|
|-i ( -이 )||-ga ( -가 )|
|-eul ( -을 )||-reul ( -를 )|
|-gwa ( -과 )||-wa ( -와 )|
|-euro ( -으로 )||-ro ( -로 )|
Some verbs may also change shape morphophonemically.
Korean is an agglutinative language . The Korean language is traditionally considered to have nine parts of speech. For details, see Korean parts of speech . Modifiers generally precede the modified words, and in the case of verb modifiers, can be serially appended. The basic form of a Korean sentence is subject–object–verb , but the verb is the only required and immovable element.
|store + [location marker ( 에 )]||[go (verb root) ( 가 )]+[conjugated (contraction rule)( 아 )]+[past ( ㅆ )]+[conjunctive ( 어 )]+ [polite marker ( 요 )]|
- "Did [you] go to the store?" ("you" implied in conversation)
|B :||예. (or 네. )|
|ye (or ne , de )|
Speech levels and honorifics
The relationship between a speaker or writer and his or her subject and audience is paramount in Korean grammar. The relationship between speaker/writer and subject referent is reflected in honorifics , whereas that between speaker/writer and audience is reflected in speech level .
When talking about someone superior in status, a speaker or writer usually uses special nouns or verb endings to indicate the subject's superiority. Generally, someone is superior in status if he/she is an older relative, a stranger of roughly equal or greater age, or an employer, teacher, customer, or the like. Someone is equal or inferior in status if he/she is a younger stranger, student, employee or the like. Nowadays, there are special endings which can be used on declarative, interrogative, and imperative sentences; and both honorific or normal sentences. They are made for easier and faster use of Korean.
Honorifics in traditional Korea were strictly hierarchical. The caste and estate systems possessed patterns and usages much more complex and stratified than those used today. The intricate structure of the Korean honorific system flourished in traditional culture and society. Honorifics in contemporary Korea are now used for people who are psychologically distant. Honorifics are also used for people who are superior in status. For example, older relatives, people who are older, teachers, and employers.
There are seven verb paradigms or speech levels in Korean , and each level has its own unique set of verb endings which are used to indicate the level of formality of a situation. Unlike honorifics —which are used to show respect towards the referent (the person spoken of) — speech levels are used to show respect towards a speaker's or writer's audience (the person spoken to). The names of the seven levels are derived from the non-honorific imperative form of the verb 하다 ( hada , "do") in each level, plus the suffix 체 ("che", hanja : 體 ), which means "style".
The highest six levels are generally grouped together as jondaenmal ( 존댓말 ), whereas the lowest level ( haeche , 해체 ) is called banmal ( 반말 ) in Korean.
Nowadays, younger-generation speakers no longer feel obligated to lower their usual regard toward the referent. It is common to see younger people talk to their older relatives with banmal ( 반말 ). This is not out of disrespect, but instead it shows the intimacy and the closeness of the relationship between the two speakers. Transformations in social structures and attitudes in today's rapidly changing society have brought about change in the way people speak.
Gender and the Korean language
In general, Korean lacks grammatical gender. (As one of the few examples, third-person singular pronoun has two different forms 그 geu (male) vs. 그녀 geunyeo (female). However, these terms were invented in the 20th century under the influence of foreign languages, and they seldom appear in colloquial speech.)
However, one can still find stronger contrasts between the genders within Korean speech. Some examples of this can be seen in: (1) softer tone used by women in speech; (2) a married woman introducing herself as someone’s mother or wife, not with her own name; (3) the presence of gender differences in titles and occupational terms (for example, a sajang is a company president and yŏsajang is a female company president.); (4) females sometimes using more tag questions and rising tones in statements, also seen in speech from children.
In Western societies, individuals tend to avoid expressions of power asymmetry, mutually addressing each other by their first names for the sake of solidarity. Between two people of asymmetrical status in a Korean society, people tend to emphasize differences in status for the sake of solidarity. Koreans prefer to use kinship terms rather than any other terms of reference. In traditional Korean society, women have long been in disadvantaged positions. Korean social structure traditionally was a patriarchically dominated family system that emphasized the maintenance of family lines. This structure has tended to separate roles of women from those of men.
The core of the Korean vocabulary is made up of native Korean words. A significant proportion of the vocabulary, especially words that denote abstract ideas, are Sino-Korean words , either
The exact proportion of Sino-Korean vocabulary is a matter of debate. Sohn (2001) stated 50–60%. Later, the same author (2006, p. 5) gives an even higher estimate of 65%. Jeong Jae-do, one of the compilers of the dictionary Urimal Keun Sajeon , asserts that the proportion is not so high. He points out that Korean dictionaries compiled during the colonial period include many unused Sino-Korean words. In his estimation, the proportion of native Korean vocabulary in the Korean language might be as high as 70%. 
Korean has two numeral systems : one native, and one borrowed from Sino-Korean.
To a much lesser extent, some words have also been borrowed from Mongolian and other languages. Conversely, the Korean language itself has also contributed some loanwords to other languages, most notably the Tsushima dialect of Japanese.
The vast majority of loanwords other than Sino-Korean come from modern times, approximately 90% of which are from English . Many words have also been borrowed from Western languages such as German via Japanese ( 아르바이트 ( areubaiteu ) "part-time job", 알레르기 ( allereugi ) "allergy", 기브스 ( gibseu or gibuseu ) "plaster cast used for broken bones"). Some Western words were borrowed indirectly via Japanese during the Japanese occupation of Korea , taking a Japanese sound pattern, for example "dozen" > ダース dāsu > 다스 daseu . Most indirect Western borrowings are now written according to current "Hangulization" rules for the respective Western language, as if borrowed directly. There are a few more complicated borrowings such as "German(y)" (see names of Germany ), the first part of whose endonym [ˈd̥ɔɪ̯t͡ʃʷ.la̠ntʰ] the Japanese approximated using the kanji 獨逸 doitsu that were then accepted into the Korean language by their Sino-Korean pronunciation: 獨 dok + 逸 il = Dogil . In South Korean official use, a number of other Sino-Korean country names have been replaced with phonetically oriented "Hangeulizations" of the countries' endonyms or English names.
Because of such a prevalence of English in modern Korean culture and society, lexical borrowing is inevitable. English-derived Korean, or ' Konglish ' ( 콩글리쉬 ), is increasingly used. The vocabulary of the Korean language is roughly 5% loanwords (excluding Sino-Korean vocabulary).
Korean uses words adapted from English in ways that may seem strange to native English speakers. For example, in soccer heading ( 헤딩 ) is used as a noun meaning a 'header', whereas fighting ( 화이팅 / 파이팅 ) is a term of encouragement like 'come on'/'go (on)' in English. Something that is 'service' ( 서비스 ) is free or 'on the house'. A building referred to as an 'apart-uh' ( 아파트 ) is an 'apartment' (but in fact refers to a residence more akin to a condominium) and a type of pencil that is called a 'sharp' ( 샤프 ) is a mechanical pencil.
North Korean vocabulary shows a tendency to prefer native Korean over Sino-Korean or foreign borrowings, especially with recent political objectives aimed at eliminating foreign influences on the Korean language in the North. In the early years, the North Korean government tried to eliminate Sino-Korean words. Consequently, South Korean may have several Sino-Korean or foreign borrowings which are not in North Korean.
Formerly, the languages of the Korean peninsula were written using hanja, called hyangchal or idu : the use of Chinese characters either as rebuses to stand for Korean words, or as synonyms for those words. Writing was confined to the ruling elite, who most often wrote only in Classical Chinese.
In the 15th century, Sejong the Great commissioned a national writing system called Hangul , but the yangban aristocracy denounced it as inferior to hanja .  Because of growing Korean nationalism in the 19th century, the Gabo Reformists ' push, and the promotion of Hangul in schools.  In 1894, hangul displaced hanja as Korea's national script.  Hanja is still used to a certain extent in South Korea where it is sometimes combined with Hangul, but this method is slowly declining in use despite Korean students learning Hanja in school. 
Below is a chart of the Korean alphabet's symbols and their canonical IPA values:
|RR||b||d||j||g||pp||tt||jj||kk||p||t||ch||k||s||h||ss||m||n||ng||r , l|
|IPA||p||t||t͡ɕ||k||p͈||t͈||t͡ɕ͈||k͈||pʰ||tʰ||t͡ɕʰ||kʰ||s||h||s͈||m||n||ŋ||ɾ , l|
Modern Korean is written with spaces between words , a feature not found in Chinese or Japanese. Korean punctuation marks are almost identical to Western ones. Traditionally, Korean was written in columns, from top to bottom, right to left, but is now usually written in rows, from left to right, top to bottom.
Differences between North Korean and South Korean
The Korean language used in the North and the South exhibits differences in pronunciation, spelling, grammar and vocabulary.
In North Korea, palatalization of /si/ is optional, and /t͡ɕ/ can be pronounced [z] between vowels.
Words that are written the same way may be pronounced differently, such as the examples below. The pronunciations below are given in Revised Romanization , McCune–Reischauer and Hangul, the last of which represents what the Hangul would be if one were to write the word as pronounced.
|North (RR/MR)||North (Hangul)||South (RR/MR)||South (Hangul)|
|읽고|| to read |
|il k o (il k o)||일코||il kk o (il kk o)||일꼬|
|압록강||Amnok River||am r okgang (am r okkang)||암록깡||am n okkang (am n okkang)||암녹깡|
|독립||independence||dong r ip (tong r ip)||동립||dong n ip (tong n ip)||동닙|
|관념||idea / sense / conception||gwa ll yeom (kwa ll yŏm)||괄렴||gwa nn yeom (kwa nn yŏm)||관념|
|혁신적*||innovative||hyeoksin jj eok (hyŏksin tch ŏk)||혁씬쩍||hyeoksin j eok (hyŏksin j ŏk)||혁씬적|
* Similar pronunciation is used in the North whenever the hanja " 的 " is attached to a Sino-Korean word ending in ㄴ , ㅁ or ㅇ . (In the South, this rule only applies when it is attached to any single-character Sino-Korean word.)
Some words are spelled differently by the North and the South, but the pronunciations are the same.
|North spelling||South spelling|
|해빛||햇빛||sunshine||haeppit (haepit)||The "sai siot" (' ㅅ ' used for indicating sound change) is almost never written out in the North.|
|벗꽃||벚꽃||cherry blossom||beotkkot (pŏtkkot)|
|못읽다||못 읽다||cannot read||modikda (modikta)||Spacing.|
|한나산||한라산||Hallasan||hallasan (hallasan)||When a ㄴㄴ combination is pronounced as ll , the original Hangul spelling is kept in the North, whereas the Hangul is changed in the South.|
|규률||규율||rules||gyuyul (kyuyul)||In words where the original hanja is spelt " 렬 " or " 률 " and follows a vowel, the initial ㄹ is not pronounced in the North, making the pronunciation identical with that in the South where the ㄹ is dropped in the spelling.|
Spelling and pronunciation
Some words have different spellings and pronunciations in the North and the South, some of which were given in the "Phonology" section above:
|North spelling||North pronun.||South spelling||South pronun.|
|력량||ryeongryang (ryŏngryang)||역량||yeongnyang (yŏngnyang)||strength||Initial r' s are dropped if followed by i or y in the South Korean version of Korean.|
|로동||rodong (rodong)||노동||nodong (nodong)||work||Initial r' s are demoted to an n if not followed by i or y in the South Korean version of Korean.|
|원쑤||wonssu (wŏnssu)||원수||wonsu (wŏnsu)||mortal enemy||"Mortal enemy" and " field marshal " are homophones in the South. Possibly to avoid referring to Kim Il-sung , Kim Jong-il or Kim Jong-un as the enemy, the second syllable of "enemy" is written and pronounced 쑤 in the North. |
|라지오||rajio (rajio)||라디오||radio (radio)||radio|
|우||u (u)||위||wi (wi)||on; above|
|안해||anhae (anhae)||아내||anae (anae)||wife|
|꾸바||kkuba (kkuba)||쿠바||kuba (k'uba)||Cuba||When transcribing foreign words from languages that do not have contrasts between aspirated and unaspirated stops, North Koreans generally use tensed stops for the unaspirated ones while South Koreans use aspirated stops in both cases.|
|페||pe (p'e)||폐||pye (p'ye), pe (p'e)||lungs||In the case where ye comes after a consonant, such as in hye and pye , it is pronounced without the palatal approximate. North Korean orthography reflect this pronunciation nuance.|
In general, when transcribing place names, North Korea tends to use the pronunciation in the original language more than South Korea, which often uses the pronunciation in English. For example:
|Original name||North Korea transliteration||English name||South Korea transliteration|
|Ulaanbaatar||울란바따르||ullanbattareu (ullanbattarŭ)||Ulan Bator||울란바토르||ullanbatoreu (ullanbat'orŭ)|
|København||쾨뻰하븐||koeppenhabeun (k'oeppenhabŭn)||Copenhagen||코펜하겐||kopenhagen (k'op'enhagen)|
|al-Qāhirah||까히라||kkahira (kkahira)||Cairo||카이로||kairo (k'airo)|
Some grammatical constructions are also different:
|North spelling||North pronun.||South spelling||South pronun.|
|되였다||doeyeotda (toeyŏtta)||되었다||doeeotda (toeŏtta)||past tense of 되다 (doeda/toeda), "to become"||All similar grammar forms of verbs or adjectives that end in ㅣ in the stem (i.e. ㅣ , ㅐ , ㅔ , ㅚ , ㅟ and ㅢ ) in the North use 여 instead of the South's 어 .|
|고마와요||gomawayo (komawayo)||고마워요||gomawoyo (komawŏyo)||thanks||ㅂ -irregular verbs in the North use 와 (wa) for all those with a positive ending vowel; this only happens in the South if the verb stem has only one syllable.|
|할가요||halgayo (halkayo)||할까요||halkkayo (halkkayo)||Shall we do?||Although the Hangul differ, the pronunciations are the same (i.e. with the tensed ㄲ sound).|
Some vocabulary is different between the North and the South:
|North spelling||North pronun.||South spelling||South pronun.|
|문화주택||munhwajutaek (munhwajut'aek)||아파트||apateu (ap'at'ŭ)||Apartment||아빠트 (appateu/appat'ŭ) is also used in the North.|
|조선말||joseonmal (chosŏnmal)||한국어||han-gugeo (han'gugŏ)||Korean language||한국말 is also used in the South|
|곽밥||gwakbap (kwakpap)||도시락||dosirak (tosirak)||lunch box|
|동무||dongmu (tongmu)||친구||chingu (ch'ingu)||Friend||동무 was originally a non-ideological word for "friend" used all over the Korean peninsula, but North Koreans later adopted it as the equivalent of the Communist term of address " comrade ". As a result, to South Koreans today the word has a heavy political tinge, and so they have shifted to using other words for friend like " 친구 ", " 벗 " (beot/pŏt).  |
In the North, guillemets 《 and 》 are the symbols used for quotes; in the South, quotation marks equivalent to the English ones, “ and ” , are standard, although 『 』 and 「 」 are also used.
Study by non-native learners
For native English speakers, Korean is generally considered to be one of the most difficult languages to master despite the relative ease of learning Hangul. For instance, the United States ' Defense Language Institute places Korean in Category IV, which also includes Arabic , Japanese , and Chinese . This means that 63 weeks of instruction (as compared to just 25 weeks for French , Spanish , Portuguese , and Italian ) are required to bring an English-speaking student to a limited working level of proficiency in which he or she has "sufficient capability to meet routine social demands and limited job requirements" and "can deal with concrete topics in past, present, and future tense."  Similarly, the Foreign Service Institute 's School of Language Studies places Korean in Category IV, the highest level of difficulty. 
The study of the Korean language in the United States is dominated by Korean American heritage language students ; in 2007 they were estimated to form over 80% of all students of the language at non-military universities.  However, Sejong Institutes in the United States have noted a sharp rise in the number of people of other ethnic backgrounds studying Korean between 2009 and 2011; they attribute this to rising popularity of South Korean music and television shows . 
Korean is considerably easier for speakers of certain other languages, such as Japanese; in Japan, it is more widely studied by non-heritage learners.
Korean language tests
There are two widely used tests of Korean as a foreign language: the Korean Language Proficiency Test (KLPT) and the Test of Proficiency in Korean (TOPIK). The Korean Language Proficiency Test, an examination aimed at assessing non-native speakers' competence in Korean, was instituted in 1997; 17,000 people applied for the 2005 sitting of the examination.  The TOPIK was first administered in 1997 and was taken by 2,274 people. Since then the total number of people who have taken the TOPIK has surpassed 1 million, with more than 150,000 candidates taking the test in 2012. 
The TOPIK test has three different difficulty levels: beginner, intermediate, and advanced; the difficulty level of the test taken determines the level achieved—the beginner test is levels 1 and 2; intermediate is levels 3 and 4; and advanced is levels 5 and 6. The TOPIK includes four sections: vocabulary/grammar ( 어휘및 문법 ), writing ( 쓰기 ), listening ( 듣기 ), and reading ( 읽기 ). The vocabulary/grammar section, listening section, and reading section each consist of 30 multiple choice questions worth a total of 100 points. The writing section consists of 10 multiple-choice questions worth 4 points each, and 4-6 written responses worth 60 points. The overall total score out of 400 is determined by adding up the 4 scores from each individual 100-point section. However, the level achieved is not simply a matter of achieving a minimum total score; the test-taker must achieve a minimum score in each section in addition to a minimum average total score. In order to achieve the lower of the two levels on each test (levels 1, 3, and 5), the test-taker must get at least 40 points in each of the four sections, and must get an average total score of 50 on the four sections. In order to achieve the higher of the two levels on each test (levels 2, 4, and 6), the test-taker must get at least 50 points in each of the four sections, and must get an average total score of 70 on the four sections.
