一點一點被啃掉
兩個用法共用同一個動作,只是被啃的東西一個摸得到、一個摸不到。
wear away (rock) · verb · C2
If wind, rain, or the sea erodes rock or soil, or if rock or soil erodes, the surface is slowly worn away.
侵蝕
Water or wind passing over rock again and again, taking an invisible amount each time — no single pass matters, but after years the shape is gone.
Latin erodere = ex- ('away') + rodere ('to gnaw') — the same rodere behind 'rodent'. The root picture is something being nibbled away bite by tiny bite.
拉丁文 ērōdere 由 ex-(去掉)加 rōdere(啃)組成,而 rōdere 也是 rodent(齧齒動物)的來源。所以字根裡藏的是一隻慢慢啃的動物:一口一口,每口都很小,但東西確實在變少。這正好對上現代用法的核心——不是撞碎,是啃掉。
