swath
🇺🇸 /swˈɑθ/
名词,原指镰刀割过留下的一道带状痕迹,常引申为大片连续的土地、人群或事物。
💡 记忆钩子
想象镰刀在田里划过:它先留下“一道割痕”,这道带状痕迹再扩大成地图上的“一大片土地”,或人群、观点中的“一大片范围”。
📝 学习建议
- 先掌握“大片、广泛范围”这一常见引申义,再理解它原本的农作物割痕义。
- 不要把它只理解成普通的“条纹”或“带子”;它通常强调被划过或覆盖的一大片连续范围。

common 镰刀割过的一道地带📖 指镰刀或类似工具在田地中割过后留下的带状区域;重点是“割出一道痕迹”这一画面。💡 常见结构是 a swath cut by/with a scythe,或 a swath through + 地点。这个义项主要出现在农业描写、历史叙述或文学语境中,日常对话里不如引申义常见。不要把它理解为单独的一根草或一条普通线条。The farmer cut a fresh swath through the tall grass.农夫在高高的草丛中割出了一道新鲜的带状地带。

core 大片范围📖 由“割出的一道带状地带”引申为一大片连续的土地、人群、意见或其他事物,强调范围很广、覆盖面很大。💡 最常见结构是 a large/broad/wide swath of + 名词,例如土地、人群或选民。这个用法常见于新闻和正式表达,既可指具体空间,也可指抽象群体或范围。通常要用限定词说明大小,不能把它当作泛指任何一个普通部分。figuratively oftenA broad swath of the population supports the new law.广大民众支持这项新法律。

🌳 词源
源自古英语,词根义与“割过留下的痕迹”有关;现代含义由田间割痕发展为大片范围。
From Middle English swath, swathe, from Old English swæþ, swaþu (“track; trace; footstep”), from Proto-Germanic *swaþō (“a wind-swept place; open field”), of unknown further origin. Has been derived from a Proto-Indo-European *swey- (“to bend, turn, swing”), and compared with Ancient Greek σιμός (simós, “snub-nosed”) and Welsh chwil (“reeling, staggering”), though this is uncertain, as well as the Greek comparandum being unlikely.
Cognate with Dutch zwade, zwad (“swath; windrow”), German Schwade (“swath; windrow”), Icelandic svæði (“area; zone; sector; region”).
other etymological information
Corresponds to Middle Low German and Middle Dutch swat, Middle High German and MNG swade, NDu swad(e), Old Frisian swethe (“border”).
Root meaning: trace of a cut.
Attested in English since 888 in its obsolete meaning of track or trace, since 1475 in its more modern usage.
Cognate with German Schwaden (“row of mown grass or grain”).
No definite cognates outside Germanic languages.
