Etymology: Slidery is an adjective built from "slide" and the suffix "-y," which turns a noun or verb into a description of something that has the quality of it. The verb "slide" comes from Old English "slidan," meaning to glide smoothly over a surface, so the word describes anything that behaves that way. The form is uncommon, and it appears mostly in informal and regional use rather than in the standard vocabulary. Its exact date of first use is not something I can pin down, so the usual pattern of an English adjective made from an existing verb plus "-y" is the safest account of how it came to be.

Synonyms: slippery, slithery
