It has been extinct since November 2009 when its last speaker, Boro, died. 
The native name for the language was Aka-Kora , also spelled Aka-Khora or Aka-Cora ( Aka- being a prefix for "tongue"); and this name is often used for the tribe itself. They were divided between shore-dwellers ( aryoto ) and forest-dwellers ( eremtaga ) subtribes. 
By the time of the first permanent British settlement at Port Blair (1858), the estimates size of the Kora tribe was about 500 individuals, out of perhaps 3500 Great Andamanese.  However the tribe was discovered only much later, in the work leading to the 1901 census.  Like other Andamanese peoples, the Kora were decimated during colonial and post-colonial times, by diseases, alcohol, colonial warfare and loss of territory. The census of 1901 recorded 96 individuals, which decreased to 71 in 1911, 48 in 1921, and 24 in 1931. 
By 1980 only one person claimed to be a Kora member,  and 1994 the Kora tribe no longer existed as a separate unit.  Although descendants of the Kora were still living in the Great Andamanese reservation of Strait Island as of 2006, they identified themselves as members of other tribes, mainly Jeru.  The last known speaker of the Kora language died in November 2009.  They were a designated Scheduled Tribe. 
The Great Andamanese languages are agglutinative languages, with an extensive prefix and suffix system. They have a distinctive noun class system based largely on body parts, in which every noun and adjective may take a prefix according to which body part it is associated with (on the basis of shape, or functional association). Thus, for instance, the *aka- at the beginning of the language names is a prefix for objects related to the tongue. An adjectival example can be given by the various forms of yop , "pliable, soft", in Aka-Bea:
- A cushion or sponge is ot-yop "round-soft", from the prefix attached to words relating to the head or heart.
- A cane is ôto-yop , "pliable", from a prefix for long things.
- A stick or pencil is aka-yop , "pointed", from the tongue prefix.
- A fallen tree is ar-yop , "rotten", from the prefix for limbs or upright things.
Similarly, beri-nga "good" yields:
- un-bēri-ŋa "clever" (hand-good).
- ig-bēri-ŋa "sharp-sighted" (eye-good).
- aka-bēri-ŋa "good at languages" (tongue-good.)
- ot-bēri-ŋa "virtuous" (head/heart-good)
The prefixes are,
|torso (shoulder to shins)||ab-||ab-||ab-||a-||o-|
The basic pronouns are almost identical throughout the Great Andamanese languages; Aka-Bea will serve as a representative example (pronouns given in their basic prefixal forms):
|I, my||d-||we, our||m-|
|thou, thy||ŋ-||you, your||ŋ-|
|he, his, she, her, it, its||a||they, their||l-|
'This' and 'that' are distinguished as k- and t- .
