• Use commas to separate elements in a series, but do not put a comma before the conjunction in a simple series: The flag is red, white and blue. He would nominate Tom, Dick or Harry. Put a comma before the concluding conjunction in a series, however, if an integral element of the series requires a conjunction: I had orange juice, toast, and ham and eggs for breakfast. Use a comma also before the concluding conjunction in a complex series of phrases: The main points to consider are whether the athletes are skillful enough to compete, whether they have the stamina to endure the training, and whether they have the proper mental attitude.
  • When a sentence ends in a quote, all punctuation ends inside the quotation marks. For example: Helen said, “Emory & Henry is the greatest college in the country!”
  • In writing Emory & Henry, the ampersand is always used.
  • Times are written as follows: 5 p.m., 3:30 a.m. Never use “o’clock” unless in a direct quote. Never use the double zero in expressing a time, such as 5:00 p.m. Always lowercase a.m. and p.m.
