- Hyphen
Do not use a hyphen between words that can better be written as one word: water-fowl, waterfowl. Common sense will aid you in the decision, but a dictionary is more reliable. The steady evolution of the language seems to favor union: two words eventually become one, usually after a period of hyphenation.

- Colloquialisms
If you use a colloquialism or a slang word or phrase, simply use it; do not draw attention to it by enclosing it in quotation marks. To do so is to put on airs, as though you were inviting the reader to join you in a select society of those who know better.
