beam词源中文解释

古英语 beam, 意为“活着的树”，但到了10世纪后期也指“椽子、柱子、船木”，源自原始日耳曼语 *baumaz “树”（也是古弗里西亚语 bam “树、绞刑架、横梁”、中古荷兰语 boom 、古高地德语 boum 、德语 Baum “树”的来源，也可能与古诺尔斯语 baðmr 、哥特语 bagms 有关，但其来源不明，据 Boutkan 认为可能是一个底层语词）。在古英语中，从 *-au- 到 -ea- 的转变是规则的。

“光线”这一含义在古英语中发展起来，可能是因为 Bede 使用 beam 来翻译拉丁语 columna (lucis)，即《圣经》中的“火柱”。“辐射流的方向”这一含义始于1906年。成语 on the beam 意为“朝着正确的方向前进”（1941年）最初是飞行员用来表示“按照无线电波指示的航线飞行”的术语。

“横梁”这一航海术语最早出现于13世纪初，因此也指“船的最大宽度”，俚语 broad in the beam 于1894年用于船只，用于人则表示“臀部宽阔”，始于1938年。
