Using the simplest grammatical structures possible can tighten and strengthen your sentences considerably.

Reducing a clause to an appositive, deleting unnecessary words, and replacing five words with one tighten the sentence and make it easier to read.

Using strong verbs

Be verbs (is, are, was, were, been) often result in wordiness.

Avoiding there is, there are, and it is

Sometimes expletive constructions—there is, there are, and it is—can introduce a topic effectively; often, however, your writing will be better without them.

Using active voice

Some writing situations call for the passive voice (32g), but it is always wordier than the active—and often makes for dull or even difficult reading.
