Etymology

Origin of slick

First recorded before 900 for the verb, 1350–1400 for the adjective; Middle English verb slicke(n), Old English (nīw)slīcod “(newly) polished”; Middle English adjective slik(e), slyk(e), from unrecorded Old English slice; cognate with dialectal Dutch sleek “even, smooth”; noun derivative of the verb or adjective; adverb derivative of the adjective

Explanation

Slick means smooth or slippery, but it can also describe a smooth, effortless style. How did that Girl Scout talk you into buying so many boxes of cookies? It must have been her slick sales pitch. A great salesman is often described as slick — he or she seems more like a friend than someone trying to sell you something. Things that are smooth and glossy can also be called slick, like the surface of a glass table or an icy patch on the sidewalk. Slick is also a verb, meaning "to smooth," like when you slick back your hair. The oldest meaning of slick is shiny, and in the 1620s, it was even the name of a kind of cosmetic.
