Context & Register
语域：neutral 常见场景：农业、地质学、园艺 这里针对名词义：指表土以下的土层，通常用于农业、地质、园艺等专业语境，日常口语中较少单独使用；动词义（掘起底土）则更少见且更专业。
Pronunciation & Spelling
这些词都与 subsoil 词尾 -soil 的发音 /sɔɪl/ 押韵：topsoil, boil, coil, foil, toil, spoil。注意 subsoil 的重音在 sub- 上，-soil 为次重音。拼写以 -oil 结尾的词常读 /ɔɪl/，但不要被拼写相似的 all /ɔːl/（全部）或 aisle /aɪl/（通道）误导。
