Word Origin & History
c.1200, from O.N. skaða "to hurt, injure," from P.Gmc. *skath- (cf. O.E. sceaþian "to hurt, injure," O.Fris. skethia, M.Du. scaden, Du. schaden, O.H.G. scadon, Ger. schaden, Goth. scaþjan "to injure, damage"), from PIE base *sket- "to injure." Only cognate outside Gmc. seems to be in
Gk. a-skethes "unharmed, unscathed." Survives mostly in its negative form, unscathed
, and in figurative meaning "sear with invective or satire" (1852, usually as scathing) which developed from the sense of "scar, scorch" used by Milton in "Paradise Lost" i.613 (1667).
