An honorarium is a sum of money offered to a professional for a talk, a piece of advice, or a similar service — often when that person is not sending you a normal bill. Universities, churches, and clubs offer one to a guest speaker. It is a polite payment, not a salary, and not usually a huge fee. Though actually, the word sounds grand (Latin for a gift given in honour), but the money is often modest, and in some jobs people are not allowed to take it. It is not the same as honorary, which describes a title you hold as an honour, often with no pay at all.

車馬費、演講費、出席費（對專業人士一次的謝禮，不是薪水）。中國大陸較常說「酬金」「勞務費」。
