Use the verb declaim when someone is speaking very passionately against something, like when you declaim against having to be home by 8 p.m.
Declaim can also describe reciting words aloud for practice. If you’re learning a new language, you might declaim a sentence until it sounds clear and natural when you say it. Declaim was originally spelled declame, similar to the Latin word declamare, meaning “to practice public speaking,” but later became declaim as its other meaning came into greater use.
