Learner notes
Memory Tip
联想记忆：开头是 single（单一），所以 singleton 指“只有一个”的东西，如桥牌单张、单元素集合、独身者。
Context & Register
语域：mixed 常见场景：数学/集合论、桥牌、日常叙述 该词多用于数学或桥牌等专业语境，语气偏正式；若在一般语境中指单个事物，也可作为中性表达。因正式程度随领域变化，故标记为混合。
Pronunciation & Spelling
singleton 没有常见的完全押韵词。simpleton 和 skeleton 拼写都以 -leton 结尾，但重读元音及后续辅音不同，不能押韵。button、cotton、carton 与 singleton 共享词尾 -ton，读音都是轻读 /tən/，但重读音节不同，仍不算押韵。kitten 拼写为 -ten，但词尾也读 /tən/，容易混淆。
