German scheiden (to separate, divorce) and Entscheidung (decision, literally 'a cutting-through') are direct cognates of English shed. The watershed is their clearest meeting point in English: the ridge that sheds — divides, adjudicates — the watersbetween river systems. Meanwhile sheath names the instrument of separation itself: Proto-Germanic
' was to separate it from the body. Cognates include German scheiden (to separate, divorce, part — Abschied = farewell, Entscheidung = decision = a cutting-through), Dutch scheiden, and Old Norse skeiða. The noun 'shed' — a simple outbuilding — appears much later (c. 1481) and is most likely a variant of 'shade' (OE sceadu, shadow), from a different PIE root *skot- (darkness, shadow). The two words represent a coincidental convergence: the verb from PIE *skei- (to cut/separate), the noun from PIE *skot- (shadow). Key roots: *skei- (Proto-Indo-European: "to cut, split, separate — source of shed, sheath, ski, schism"), *skaidijaną (Proto-Germanic: "to separate, divide — direct ancestor of OE scēadan and German scheiden").
