smallness = small（小）+ ness（名词后缀），记住把形容词 small 变成名词，就指“小、少量、小气”这些与“小”相关的状态。
语域：formal 常见场景：学术写作、文学描写、正式报告 smallness 是形容词 small 派生的抽象名词，多用于书面或正式语境，常见于学术写作、文学描写和正式报告；日常口语中较少单用，而更常说 how small something is 等表达。
这些词都以 -ness 结尾。happiness、darkness、kindness、weakness、illness 的 -ness 均读 /nɪs/，与 smallness 的结尾相同；但重音不同，因此严格说不是整词押韵。注意 business 是拼写陷阱：它有 -ness 拼写，却读 /ˈbɪznɪs/（近似“biz-ness”），其中的 i 并不构成独立音节。
