This word I used recently as a means of describing one's clothing and how it fits on the person. While the definition may not relate, the use is still proper and fun.
Accentuate, as a verb, means to emphasize or stress.
As a transitive verb, it means to pronounce with a stress or accent, to mark with an accent, or to emphasize intensity. It can also mean to single out something as being most important.
However which way you wish to use this word is up to you. It may very well Accentuate your prose.
