If the structure of a sentence is needlessly indirect, try simplifying it. Look for opportunities to strengthen the verb.
The verb estimate is more vigorous and more concise than make an estimate of.
Basic forms of be verbs (such as is, are, was, and were) frequently generate excess words.
The revision is more direct and concise. Actions orginally appearing in subordinate structures have become verbs replacing is.
Sometimes the empty verb is part of an expletive construction (such as there is, it was).
Verbs in the passive voice may be needlessly indirect. When the active voice expresses your meaning as well, use it.
