Etymology 1

The noun is derived from Middle English sclate, slat, slate (“type of rock; roofing slate; writing slate”), from Old French esclate, a feminine form of esclat (“broken piece, shard”) (modern French éclat), from Old French esclater (“to break, shatter”), from Frankish slaitijan (“to split, break”), from Proto-Germanic slaitijaną, the causative of *slītaną (“to cut up, split”); further etymology unknown (see the Proto-Germanic entry for a discussion). Doublet of éclat and slat. The adjective and verb are derived from the noun.

Etymology 2

The verb is probably derived from slate (“flake or piece of certain types of stone that tend to cleave into thin layers; fine-grained homogeneous sedimentary rock which cleaves easily into thin layers”, noun) (etymology 1; possibly alluding to the sharpness of such rock). The noun is derived from the verb.

Etymology 3

From Middle English slaiten, slat, slate (“to set (a dog) on an animal”), from Old Norse sleita, possibly related to Proto-Germanic slītaną (“to tear apart”), further etymology unknown.

Etymology 4

Possibly borrowed from Scots slait, slate (“dirty, slovenly, or objectionable person”), further etymology unknown.
