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.

The principle of parallel construction This principle, that of parallel construction, requires that expressions similar in content and function be outwardly similar. Blessed are the poor in spirit; for theirs in the kingdom of Heaven. Blessed are they that mourn; for they shall be comforted. Blessed are the meek; for they shall inherit the earth.
