PARALLEL STRUCTURE

When the structure of a sentence is simple and uniform, the important
words strike the eye at once. Compare the following:

Parallel: Beggars must not be choosers.

Confusing: Beggars must not be the one who choose.

A reader gives attention partly to the structure of a sentence, and
partly to the thought. The less we puzzle him with our structure, the
more we shall impress him with our thought.

Parallel: Seeing is believing. [Attention goes to the thought.]

Confusing: Seeing is to believe. [Attention is diverted to
_structure_.]

The reader's expectation is that uniform structure shall accompany
uniform ideas, and that a departure from uniformity shall indicate a
change of thought.

=Parallel Structure for Parallel Thoughts=

=30. Give parallel structure to those parts of a sentence which are
parallel in thought. Do not needlessly interchange an infinitive with a
participle, a phrase with a clause, a single word with a phrase or
clause, a main clause with a dependent clause, one voice or mode of the
verb with another, etc.=
