To shout — loudly, at length, and usually because you are angry or complaining. It is a rare, bookish word, the kind you meet in a nineteenth-century novel or in writing that is being deliberately grand or a little funny about someone's temper. A crowd vociferates against a decision; an angry customer vociferates at the counter. If you use it in ordinary conversation, people will notice, and depending on the room they may find it amusing. The word carries the picture of noise being carried out and thrown at someone, not just a raised voice. In real modern English you would say "shout", "yell", or "rant". Know it so you can read it; the related adjective "vociferous" is far more alive and is the one you will actually see in newspapers.
