Other forms: licking, licks, licked
To lick is to run your tongue over something. An ice cream on a hot day, a stamp, a dog licking your hand, a child licking the spoon clean before anyone can stop her.
There is a noun too: give it a lick, and a lick of paint, which means a quick thin coat rather than a proper job. Flames lick, moving over a surface the way a tongue does, and waves lick the side of a boat. In music a lick is a short showy phrase, the kind a guitarist drops into a solo. Two informal senses are worth recognising without writing: lick can mean to beat someone in a fight or a game, and to lick your wounds is to go off quietly and recover after a defeat.

Too few real examples of this word to estimate which sense is commonest.
Lick is very old and barely changed: Old English liccian, from Proto-Germanic *likkōną, from a Proto-Indo-European root *leyǵʰ- that already meant "to lick". Its cousins line up across Europe, in German lecken, Dutch likken, French lécher and Italian leccare. The violent sense, licking someone in a fight, is a mystery, and no other Germanic language did the same thing.
