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"). Slogans vary from the written and the visual to the chanted and the vulgar. Their simple rhetorical nature usually leaves little room for detail. A chanted slogan may serve more as social expression of unified purpose than as communication to an intended audience.
