thatch的词源

英文词源

thatch: 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.
=> deck, detect, integument, protect, thug, tile, toga
thatch (v.): late 14c., thecchen, from Old English þeccan "to cover, cover over, conceal," in late Old English specifically "cover the roof of a house," related to þæc "roof, thatching material," from Proto-Germanic *thakan (cognates: Old Saxon thekkian, Old Norse þekja, Old Frisian thekka, Middle Dutch decken, Dutch dekken, Old High German decchen, German decken "to cover"), from PIE *(s)teg- (2) "to cover" (see stegosaurus).
thatch (n.): Old English þæc "roof, thatch, cover of a building," from the source of thatch (v.). Compare Old Norse þak, Old Frisian thek, Swedish tak, Danish tag, Middle Dutch, Dutch dak "roof," Old High German dah "covering, cover," German Dach "roof."

它的根义是“覆盖”，和词根-tect-“覆盖”同源；体会这里的th、t音变和ch、c音变，前者如thin（薄的；瘦的）—tense（紧张的；绷紧的），后者如search（搜索）—circle（圆圈）。词根-tect-：detect（探测；察觉）、protect（保护）、deck（甲板）等。
