语域：neutral 常见场景：formal writing、public debate、philosophical or religious discussion 该词为中性词汇，通常用于正式或一般书面场合以及公开讨论中，日常口语中也较为自然。多指对某事持怀疑或不置可否态度的人，在宗教语境中可指不相信宗教的人。
与 doubter 押韵的词有 outer、shouter，它们都以 /aʊtə/ 结尾。doubt、doubtful 含有 d-o-u-b-t 拼写，b 不发音，读作 /daʊt/，但缺少 -er，所以不与 doubter 押韵。注意 doubling 拼写以 doub 开头，但 b 发音，读 /ˈdʌblɪŋ/，与 doubt 读音不同。
