當作建材的木頭
核心本身，以及它往前後兩端的自然延伸：從林中的樹，到成材的木料，到屋子裡的那根樑。

木材

木頭被當成「蓋東西的料」在看。同樣一棵樹，你若看的是它的葉子和影子，那是 tree；你若看的是它能鋸成幾根樑、撐得起哪面牆，那就是 timber。這個字的重心一直放在「拿來蓋、拿來做」這個用途上，所以它可以往前延伸到還沒砍的那片林子，也可以往後延伸到已經架上屋頂的那根樑。From the word’s history
Old English timber meant 'building material, the act of building' — the wood-sense came from the building-sense, not the other way round; it traces to a root about building and arranging (compare Latin domus, 'house').
古英語的 timber 原本指的是「建材、蓋房子這件事」，字根跟「建造、安排」有關（跟拉丁文 domus「房子」同源）。也就是說，這個字是先有「蓋」的意思，才用來指蓋房子用的木頭——這正好解釋了為什麼 timber 從來不是泛指木頭，而始終黏著「拿來造」這個用途。
