Etymology

Origin of vow

1250–1300; Middle English < Anglo-French, Old French vo ( u ) < Latin vōtum, neuter of vōtus, past participle of vovēre to vow

Explanation

To vow is to make an earnest promise or pledge. People getting married often vow to stick together “till death do us part,” while a presidential candidate might vow to lower taxes. You can use vow as both a noun and a verb: A vow is a solemn declaration; to vow is the act of making that promise. Vows are meant to be serious, sacred things, even vows made with the best intentions can be broken. Wrote American short-story writer and poet Dorothy Parker, “By the time you swear you are his, shivering and sighing, And he vows his passion is infinite and undying—Lady, make a note of this: One of you is lying.”
