A slogan is a memorable motto or phrase. It is often used in a political, commercial, religious, and other context as a repetitive expression of an idea or purpose. The word slogan is derived from "slogorn" which was an Anglicisation of the Scottish Gaelic "sluagh-ghairm tanmay" ("sluagh" "army", "host" + "gairm" "cry") meaning something an army chanted while fighting, to keep them all cooperating.
