## Origin

**Meanings 1–3, 5–6** — From Middle English schelfe, probably from Old English scylfe ("shelf, ledge, deck of a ship"), going back through Proto-West Germanic and Proto-Germanic to a Proto-Indo-European root meaning "to cut." It is distantly related to sculpt, carve, and shell, and cognate with Dutch schelf ("hay loft") and Old Norse skjalf ("bench").
**Meaning 4** — Of obscure origin, evidently identical to Middle English shelp ("sandbar in a river"), but the sound shift is unexpected. Shelp might come from Old English scylp ("crag") or Middle Dutch schelp-.
