记忆技巧Memory Tip
记住 in- 表“不”，effect 是“效果”，-ness 名词化：没效果就是 ineffectiveness（无效）。
语境与语域Context & Register
语域：neutral 常见场景：academic writing、policy reports、general discussion ineffectiveness 是 ineffective 的名词形式，表示“无效”的状态。该词比较中性，但多用于书面或正式场合，如报告、文章和讨论中；日常口语里更常说 it doesn't work 或 how ineffective it is。
发音与拼写Pronunciation & Spelling
Only effectiveness rhymes with ineffectiveness (stressed /fɛk/ plus /tɪvnəs/). The other -ness words share the unstressed suffix /nəs/ but have different stressed vowels, so they are spelling matches, not rhymes. Ineffective looks similar but lacks the final /nəs/ and ends in /tɪv/, so it does not rhyme.
