1. Wordy, prolix, redundant, pleonastic all mean using more words than necessary to convey a desired meaning. Wordy, the broadest and least specific of these terms, may, in addition to indicating an excess of words, suggest a garrulousness or loquaciousness: a wordy, gossipy account of a simple incident. Prolix refers to speech or writing extended to great and tedious length with inconsequential details: a prolix style that tells you more than you need or want to know. Redundant and pleonastic both refer to unnecessary repetition of language. Redundant has also a generalized sense of “excessive” or “no longer needed”: the dismissal of redundant employees. In describing language, it most often refers to overelaboration through the use of expressions that repeat the sense of other expressions in a passage: a redundant text crammed with amplifications of the obvious. Pleonastic, usually a technical term, refers most often to expressions that repeat something that has been said before: “A true fact” and “a free gift” are pleonastic expressions.
