The Twenty Most Common Errors



Check your sentences to see which ones open with an introductory word, phrase, or clause. Readers usually need a small pause between the introductory element and the main part of the sentence, a pause most often signaled by a comma. Try to get into the habit of using a comma after every introductory element, be it a word, a phrase, or a clause. When the introductory element is very short, you don't always need a comma after it. But you're never wrong if you do use a comma.
