The three dots are called ellipsis, and are used indicate that something has been left out of a sentence. For example, in William Wordsworth’s lyric poem, he writes: “I wandered lonely . . .”. The ellipsis indicates that something has been left out – in this case the missing words are: “as a cloud.”.
The ellipsis has three dots, and is used either with spaces between each ellipsis point, or as a three-letter word ( . . . or … ). Either style is acceptable, but be consistent. My preferred style is to use spaces.
Whichever style you use, please remember: the ellipsis is never more than three dots!
