A person who makes an affidavit; someone who swears to the truth of a statement under oath.
From the Latin 'affidare' (to trust, pledge), through Old French 'afiant,' meaning one who makes an oath. The legal term was formalized in English courts.
In legal documents, you're the 'affiant' when you swear something is true under oath—the word itself comes from 'faith,' reminding us that oaths are fundamentally about trusting your word!
