Word Origin for slate
C14: from Old French esclate, from esclat a fragment; see slat1
mid-14c., from Old French esclate, fem. of esclat "split piece, splinter" (Modern French éclat; see slat), so called because the rock splits easily into thin plates. As an adjective, 1510s. As a color, first recorded 1813. Sense of "a writing tablet" (made of slate), first recorded late 14c., led to that of "list of preliminary candidates prepared by party managers," first recorded 1842, from notion of being easily altered or erased. Clean slate (1856) is an image from customer accounts chalked up in a tavern.
v.
1520s, "to cover with slates" (earlier sclatten, late 15c.), from slate (n.). Meaning "propose, schedule" is from 1883; earlier "to nominate" (1804); the notion is of writing on a slate board. Related: Slated; slating.
A fine-grained metamorphic rock that forms when shale undergoes metamorphosis. Slate splits into thin layers with smooth surfaces. It ranges in color from gray to black or from red to green, depending on the minerals contained in the shale from which it formed.
