 91  On February 14 many couples give each other candy or flowers. OR On February 14, many couples give each other candy or flowers. Rule 11. If something or someone is sufficiently identified, the description following it is considered nonessential and should be surrounded by commas. Examples: Freddy, who has a limp, was in an auto accident. Freddy is named, so the description is not essential. The boy who has a limp was in an auto accident. We do not know which boy is being referred to without further description; therefore, no commas are used. Rule 12. Use a comma to separate two strong clauses joined by a coordinating conjunction—and, or, but, for, nor. You can omit the comma if the clauses are both short. Examples: I have painted the entire house, but he is still working on sanding the doors. I paint and he writes. Rule 13. Use the comma to separate two sentences if it will help avoid confusion. Example: I chose the colors red and green, and blue was his first choice. Rule 14. A comma splice is an error caused by joining two strong clauses with only a comma instead of separating the clauses with a conjunction, a semicolon, or a period. A run-on sentence, which is incorrect, is created by joining two strong clauses without any punctuation. Incorrect: Time flies when we are having fun, we are always having fun. (Comma splice) Incorrect: Time flies when we are having fun we are always having fun. (Run-on sentence) Correct: Time flies when we are having fun; we are always having fun. OR Time flies when we are having fun, and we are always having fun. (Comma is optional because both strong clauses are short.) 91 |
