Context & Register
语域：neutral 常见场景：construction、home repair、industrial maintenance sealant 在此取“密封胶/密封材料”的通用义，属于中性偏正式的科技类词，常见于建筑、工程、家居维修等书面说明或产品标签；日常口语中较少单独使用，多会直接说具体产品名。选择 neutral 作为默认即可。
Pronunciation & Spelling
tenant 和 important 与 sealant 一样以非重读的 /-ənt/ 结尾，但重音元音不同，所以并不押韵。excellent 和 prevalent 以 /-ələnt/ 结尾，拼写和读音都接近 sealant 的 /-lənt/，但不是严格押韵。silent 和 giant 是易混的形近词：它们发 /aɪ/，而 sealant 发 /iː/。
