skin (n.) Look up skin at Dictionary.com
c.1200, "animal hide" (usually dressed and tanned), from Old Norse skinn "animal hide," from Proto-Germanic *skintha- (cf. Old High German scinten, German schinden "to flay, skin;" German dialectal schind "skin of a fruit," Flemish schinde "bark"), from PIE *sken- "cut off" (cf. Breton scant "scale of a fish," Irish scainim "I tear, I burst"), from root *sek- "cut." Replaced native hide (n.); the modern technical distinction between the two words is based on the size of the animal. Meaning "epidermis of a living animal or person" is attested from mid-14c.; extended to fruits, vegetables, etc. late 14c.
