Etymology

From Middle English wolle, from Old English wull, from Proto-West Germanic wullu, from Proto-Germanic wullō, from Proto-Indo-European *h₂wĺ̥h₁neh₂. Cognates Cognate with Saterland Frisian Wulle, German Low German Wull, Dutch wol, German Wolle, Norwegian ull; also Welsh gwlân, Latin lāna, Lithuanian vi̇̀lna, Russian во́лос (vólos), Slovak vlna, Bulgarian влас (vlas), Albanian lesh (“wool, hair, fleece”). Doublet of lana. The vowel development u → o → oo is purely graphical. Modern English generally avoids the string ⟨wu⟩ in favour of ⟨wo⟩, and the resulting woll was then altered to wool (as supposedly better representing the pronunciation).
