If you have a long word, see if a native short one can be put in its place which will be more natural and stronger.

Avoid a Latin vocabulary and use a plain English one--short words instead of long ones.
Most of all, use _idioms_--English idioms of force.

Say an agreement was "come to." Don't say it was "consummated." For the difference between idioms and a Latin style, compare Lincoln with George Washington.

One's always interesting and convincing.

The other is dull in spite of all his good sense.
