Vary your sentence openings
Provide some variety
Clarity

When a rough draft is filled with too many sentences that begin the same way or have the same structure, try injecting some variety — as long as you can do so without sacrificing clarity or ease of reading.

15a Vary your sentence openings.

Most sentences in English begin with the subject, move to the verb, and continue to the object, with modifiers tucked in along the way or put at the end. For the most part, such sentences are fine. Put too many of them in a row, however, and they become monotonous.

Words, phrases, or clauses modifying the verb can often be inserted ahead of the subject.

Adjectives and participial phrases can frequently be moved to the beginning of a sentence without loss of clarity.

NOTE: When beginning a sentence with an adjective or a participial phrase, make sure that the subject of the sentence names the person or thing described in the introductory phrase. If it doesn’t, the phrase will dangle. (See 12e.)
