* Scottish Gaelic: The word comes from the Scottish Gaelic phrase "sluagh-ghairm". This translates literally to "war cry" or "cry of the army".
* Early Uses: The term was initially used in the context of battle cries and rallying cries, particularly in the Highlands of Scotland.
* Evolution into Commercial Use: Over time, the term's meaning broadened. In the late 19th century, it began to be used for short, catchy phrases used in advertising and political campaigns. This shift likely occurred because slogans, like war cries, served to rally and motivate people, albeit in a more commercial context.
So, while the word itself originated in the Scottish Highlands, its application in modern usage has expanded significantly, becoming an integral part of marketing and communication.
