smooth（光滑）+ -ness（名词后缀）= 光滑的名词形式，记住光滑的表面就是 smoothness。
语境与语域Context & Register
语域：mixed 常见场景：everyday descriptions of textures or surfaces、mathematical analysis (differentiability, modulus of smoothness) smoothness 在不同语境中语域变化明显：日常谈论物体表面光滑、手感顺滑时属于普通中性表达，多用于口语和一般写作；在数学中则是正式术语，指可微性类别或由光滑模度量的量。因此不宜简单归为正式或非正式，需根据学科或话题判断。
发音与拼写Pronunciation & Spelling
No common word rhymes exactly with 'smoothness' /ˈsmuːðnɪs/. 'smooth' and 'smoothly' share the stressed syllable /smuːð/; 'soothe' shares the /uːð/ sound. 'darkness', 'happiness', and 'roughness' share only the unstressed suffix /nɪs/ and do not rhyme. Watch out for lookalikes such as 'toothless' /ˈtuːθləs/, which has /θ/ instead of /ð/.
