From Middle English scateren, skateren, (also schateren, see shatter), from Old English *sceaterian, probably from a dialect of Old Norse. Possibly related to Proto-Indo-European *skey-(“to cut, split, shatter”). Compare Middle Dutch scheteren(“to scatter”), Low German schateren, Dutch schateren(“to burst out laughing”); and is apparently remotely akin to Ancient Greek σκεδάννυμι(skedánnumi, “scatter, disperse”). [1] Doublet of shatter.
