1 When talking about a general direction, the word is often not capitalised, example: the north side of the house. 2  Place names are capitalised: East Sussex, West Virginia, South Africa.

In Chicago style, you capitalize the first letter after the colon only when the colon introduces two or more sentences. âI know what you did last summer: You did nothing. You were a couch potato.â. And in case youâre not clear on when to use a colon instead of, say, a dash or a semicolon or to start a new sentence.
