Some writers think that using indirect, grandiose-sounding vocabulary strengthens a piece of writing. Nothing could be further from the truth. The more simple and direct a word the better, because it doesn't leave any room in the reader's mind for interpretation. Simple and direct does not mean simplistic or naive. Rather, it involves the use of non-pretentious vocabulary that means exactly what you intend it to mean.

Instead of accompany — use go with
Instead of appeared — use looked or seemed
Instead of arrive — use come
Instead of complete — use finish
Instead of manner — use way
Instead of transform — use change
Instead of prepare — use get ready
Instead of possess — use have
Instead of questioned — use asked
Instead of verify — use check
