scatter: [13] Scatter originally meant ‘squander’, and appears to have started life as an alteration of shatter. It first appears in northern and Scottish texts, and so the change from /sh/ to /sk/ is probably due to Norse influence. The origins of shatter [12] itself are not known. => shatter

mid-12c. (transitive), possibly a northern English variant of Middle English schateren (see shatter), reflecting Norse influence. Intransitive sense from early 15c. Related: Scattered; scattering. As a noun from 1640s.
