thatch: [OE] To thatch a building is etymologically to ‘cover’ it; the notion of ‘straw’ is a secondary development. The word goes back ultimately to the Indo-European base *tog-, *teg- ‘cover’ (source also of English detect, integument, protect, tile, and toga). Its Germanic descendant was *thak- (source of German dach ‘roof’ and English deck). From this was derived *thakjan, which gave English thatch.
