Introductory Phrases
Before a series of items in a list
Introductory Phrase or Clause Followed by Colon
| WITHIN TEXT | SEPARATED FROM TEXT – BULLETED LIST |
|---|---|
After an introductory sentence, place a colon before a list of items. Separate word or phrase items with a comma; separate longer phrase or clause items with a semicolon. Use an in-text list when the list is limited; or if wanting to keep the overall format of the document. (See Bulleted Lists.) |
Introduce the list with an introductory phrase or clause and a colon. Optionally, omit articles (a, an, the) from the beginning of list items. (Also, note exception below using a period after the intro.) Make sure that each list item reads grammatically with the introductory phrase or clause. If a list has fewer than three items, use a sentence instead of a list.(CMOS 6.127- 6.130) (Gregg 189) (APA 3.04) |
