• suggestion

  The most common and informal of the three; a tentative idea offered for others to think about, often used to soften advice or a request.

  三者中最常见、最口语化的词；指提出来供人考虑的、带试探性的想法，常用来缓和建议或请求的语气。

  Her suggestion to start the day with a short walk really helped.

  她提议每天以一段短短的散步开始新的一天，真的很有帮助。

• proposition

  More formal than suggestion; a fuller proposal or plan, often in business or negotiation, that the listener is expected to accept or reject as a whole.

  比 suggestion 更正式，通常指商业或谈判场合中提出的、较完整的提案或计划，听者需要整体接受或拒绝。

  The union rejected management's proposition to freeze wages for two years.

  工会拒绝了管理层提出的、两年内冻结工资的提案。

• proffer 本词

  A formal, literary noun for something voluntarily offered or extended, such as help, an apology, or money; rarely used as a noun in everyday speech (usually the verb 'proffer').

  是一个正式、带文学色彩的名词，指主动奉上或伸出的某物，例如帮助、道歉或金钱；日常口语中很少作名词使用（通常用作动词“proffer”）。

  He made a nervous proffer of apology, but she just walked away.

  他紧张地做出了一个道歉的表示，但她只是转身走开了。

All three mean an idea or offer for someone to consider. Suggestion is common and casual. Proposition is more formal, often a full business offer to accept or reject as a whole. Proffer is literary, now used almost only as a verb.

这三个词都表示“提出来供人考虑的想法、提议或主动提供的东西”，但语域和典型用法不同：suggestion 最日常随意，proposition 更正式、常见于需要整体接受或拒绝的商业或谈判提案，proffer 则是书面语，现代英语中几乎只作动词使用，作名词极少见。这里不比较 suggestion 表示“一丝迹象”（如 a suggestion of sadness）、proposition 在逻辑学中表示“命题”或口语中表示“棘手的任务”、以及 proffer 常见动词用法（如 to proffer help）等其他义项。
