A slogan is a memorable motto or phrase used in a clan, political, commercial, religious, and other context as a repetitive expression of an idea or purpose, with the goal of persuading members of the public or a more defined target group. The Oxford Dictionary of English defines a slogan as "a short and striking or memorable phrase used in advertising."^[1] A slogan usually has the attributes of being memorable, very concise and appealing to the audience.^[2]

The word slogan is derived from slogorn which was an Anglicisation of the Scottish Gaelic and Irish sluagh-ghairm (sluagh "army", "host" + gairm "cry").^[3] Slogans vary from the written and the visual to the chanted and the vulgar. Their simple rhetorical nature usually leaves little room for detail and a chanted slogan may serve more as social expression of unified purpose than as communication to an intended audience.

George E. Shankel's (1941, as cited in Denton Jr., 1980) research states that, "English-speaking people began using the term by 1704."

The term at that time meant "the distinctive note, phrase or cry of any person or body of persons."

Slogans were common throughout the European continent during the Middle Ages; they were used primarily as passwords to ensure proper recognition of individuals at night or in the confusion of battle.^[4]

Crimmins' (2000, as cited in Dass, Kumar, Kohli, & Thomas, 2014) research suggests that brands are an extremely valuable corporate asset, and can make up a lot of a business's total value.

With this in mind, if we take into consideration Keller's (1993, as cited in Dass, Kumar, Kohli, & Thomas, 2014) research, which suggests that a brand is made up of three different components.

These include, name, logo and slogan.

Brands names and logos both can be changed by the way the receiver interprets them.

Therefore, the slogan has a large job in portraying the brand (Dass, Kumar, Kohli, & Thomas, 2014).^[5] Therefore, the slogan should create a sense of likability in order for the brand name to be likable and the slogan message very clear and concise.

Dass, Kumar, Kohli, & Thomas' (2014) research suggests that there are certain factors that make up the likability of a slogan.

The clarity of the message the brand is trying to encode within the slogan.

The slogan emphasizes the benefit of the product or service it is portraying.

The creativity of a slogan is another factor that had a positive effect on the likability of a slogan.

Lastly, leaving the brand name out of the slogan will have a positive effect on the likability of the brand itself.^[5] Advertisers must keep into consideration these factors when creating a slogan for a brand, as it clearly shows a brand is a very valuable asset to a company, with the slogan being one of the three main components to a brands' image.

The original usage refers to the usage as a clan motto among Highland clans.

Marketing slogans are often called taglines in the United States or straplines in the United Kingdom. Europeans use the terms baselines, signatures, claims or pay-offs.^[6] "Sloganeering" is a mostly derogatory term for activity which degrades discourse to the level of slogans.

Slogans are used to convey a message about the product, service or cause that it is representing.

It can have a musical tone to it or written as a song.

Slogans are often used to capture the attention of the audience it is trying to reach.

If the slogan is used for commercial purposes, often it is written to be memorable/catchy in order for a consumer to associate the slogan with the product it is representing.^[7][8] A slogan is part of the production aspect that helps create an image for the product, service or cause it's representing. A slogan can be a few simple words used to form a phrase that can be used in a repetitive manner. In commercial advertising, corporations will use a slogan as part of promotional activity.^[8] Slogans can become a global way of identifying good or service, for example Nike's slogan 'Just Do It' helped establish Nike as an identifiable brand worldwide.^[9]

Slogans should catch the audience's attention and influence the consumer's thoughts on what to purchase.^[10] The slogan is used by companies to affect the way consumers view their product compared to others.

Slogans can also provide information about the product, service or cause its advertising.

The language used in the slogans is essential to the message it wants to convey.

Current words used can trigger different emotions that consumers will associate that product with.^[10] The use of good adjectives makes for an effective slogan; when adjectives are paired with describing nouns, they help bring the meaning of the message out through the words.^[11] When a slogan is used for advertising purposes its goal is to sell the product or service to as many consumers through the message and information a slogan provides.^[12] A slogan's message can include information about the quality of the product.^[12] Examples of words that can be used to direct the consumer preference towards a current product and its qualities are: good, beautiful, real, better, great, perfect, best, and pure.^[13] Slogans can influence that way consumers behave when choosing what product to buy.

Slogans offer information to consumers in an appealing and creative way.

A slogan can be used for a powerful cause where the impact of the message is essential to the cause.^[14][15] The slogan can be used to raise awareness about a current cause; one way is to do so is by showing the truth that the cause is supporting.^[15] A slogan should be clear with a supporting message. Slogans, when combined with action, can provide an influential foundation for a cause to be seen by its intended audience.^[16] Slogans, whether used for advertising purpose or social causes, deliver a message to the public that shapes the audiences' opinion towards the subject of the slogan.

"It is well known that the text a human hears or reads constitutes merely 7% of the received information.

As a result, any slogan merely possesses a supportive task."

(Rumšienė & Rumšas, 2014).^[17] Looking at a slogan as a supportive role to a brands image and portrayal is helpful to understand why advertisers need to be careful in how they construct their slogan, as it needs to mold with the other components of the brand image, being logo and name.

For example, if a slogan was pushing towards "environmentally friendly," yet the logo and name seemed to show very little concern for the environment, it would be harder for the brand to integrate these components into a successful brand image, as they would not integrate together towards a common image.
