- 1告訴人、原告（法庭／正式申訴用語，不是日常「愛抱怨的人」）
In a court, the complainant is the person who starts things by making a formal complaint: they say, in the official way, that someone has wronged them and they want the law to look at it. It is legal English, not kitchen-table English. A neighbour who grumbles about noise is not a complainant unless they have actually gone to the police, a government office, or the court. In a criminal case this is often the person who reports the harm; in some civil cases it is another name for the person bringing the claim. Lawyers, judges, and news reports about trials use it. The everyday verb complain is much wider — you can complain about food, weather, homework. This noun is narrower and more official: it names a role in a case.
From the word’s history
From Old French complaignant, present participle of complaindre.
源自古法文 complaignant，即 complaindre「申訴」的分詞。
組成From Old French complaignant, the “who is complaining” form of complaindre (to complain). The word is built as “the one making the complaint.”
