affidavit 宣誓書（台灣日常常把類似書面保證叫「切結書」，但切結書不一定是對法院宣誓）｜字脈

1
An affidavit is a written statement that you swear is true, so it can be used as proof in a court of law — and in other official places that want that same kind of sworn writing. You do not just fill in a form. You put the facts on paper and swear, often before a person the law trusts, that they are true; lying can bring real trouble. Lawyers, courts, and immigration offices use the word. Ordinary people meet it when a process suddenly asks for one. It is a noun, not a verb: you make an affidavit, or swear an affidavit. You do not affidavit something. The stress sits on DAY: af-fi-DAY-vit.
