You've probably heard the joke "Don't use a big word when a minuscule one will do." Ironic, huh? Big
words are like fine jewels: Once in a while you take them out of the case to admire them, but you don't actually
wear them. I advocate making prose as efficient as possible. Consider the following:
Upon. In almost all cases, the word should be on. There's no good reason to use upon.
Prior to and following. The words before and after express the same thing, and they're more efficient. I usually allow prior to in most extremely technical texts, but in general, before is the better choice.
Individual. The word is person or people. Individual is a big, multisyllabic way of saying person. But again, if an author has used individual in a very technical manuscript, I let it stand. If it's a trade manuscript or a physical education book or an STM book that will be sold in a trade market, use person or people.
Utilize. Use the word use.
An historic. Are you an happy person? I didn't think so. The h in historic is pronounced; therefore the indefinite article is a: a historic.
Entitled. This one is also a common usage error. You are entitled to your own opinion, but the movie is titled Citizen Kane. Entitle means to furnish with a right to something. Title, as a verb, is the correct choice when referring to the name of something.
