Verbosity is the quality of using too many words to say something — more words than the idea needs. If a report takes ten pages to say what a page could say, you can say the report suffers from verbosity, or complain about the verbosity of the writer. It is a noun for a fault, so it almost always carries a small criticism: nobody praises verbosity. It is a formal, bookish word. You meet it in writing about writing — teachers marking essays, editors talking about a draft, reviewers describing a novel. In ordinary speech people just say "he talks too much" or "it's too wordy"; they don't say "his verbosity." There is one place where it is not a criticism at all: in computing, the verbosity of a program or a command means how much detail it prints out while it runs, and you can turn it up or down. A programmer saying "increase the verbosity" only means "show me more messages," with no complaint in it. The related adjective is verbose, which is far more common than the noun; if you learn only one of the two, learn verbose.
