Suggest, advise, and propose all mean to offer an idea, but formality differs. Suggest is common and neutral. Advise means the speaker has expertise and speaks to a person directly. Propose is more formal, for meetings or business. Not compared: propose (marriage), advise (to inform).

这三个词都表示提出想法或计划供人考虑，但语气和正式程度不同：suggest 最普通、随意；advise 强调说话者具有专业知识或权威，并直接针对某人给出意见；propose 更正式，常用于会议、商务或正式场合提出方案。这里不比较 propose 的“求婚”义项，也不比较 advise 的“通知”义项。
