Omit needless words When a sentence is made stronger, it usually becomes shorter. Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts. This requires not that the writer make all sentence short, or avoid all detail and treat subjects only in outline, but that every word tell. William Strunk Jr. & E.B.
