Verbosity
Verbosity or verboseness is speech or writing which uses more words than needed. A common example is "Despite the fact that" as a common replacement for "Although". Antonyms of verbosity include succinctness, concision, laconism, and plain language.
Some teachers, including the author of The Elements of Style, warn writers not to be verbose. Similarly, some authors, including Mark Twain and Ernest Hemingway, are known for their succinct styles and avoidance of verbosity.
