Foreign and technical terms should be used with care.
Use idioms wherever it is possible.
Coherence demands that the parts shall be so connected that the thought will be clear and compact.
The length of sentences is governed by the effect to be produced. Short sentences give vigor, emphasis, and rapidity. Long sentences give weight and rhythm.
A well-constructed sentence keeps the same subject as long as possible.
All modifying elements should be placed as near as possible to the words they modify.
A Dangling Element—one that modifies nothing—must be avoided. Example: Looking into the water, a fish was seen.
A “Squinting Construction” is one that is so poorly placed in the sentence as to modify equally well the part preceding and the part following. Example: Will you say to Mr. Brown, when he comes, I will be ready.
Redundancy—A weak repetition of an idea—must be avoided.
Pleonasm consists in the addition of words which can be omitted without affecting the construction or the meaning of the sentence.
