Dot dot dot

In typography, an ellipsis is, as its common name suggests, a series of three dots. It has several uses, and its placement can convey a great deal of information by the very fact of taking the place of words that are absent. Primarily, it indicates an intentional omission of words from a larger text without changing the meaning. This can be an unfinished thought, a leading statement, a pause, a feeling. As for style, I use the option+semicolon keyboard command, which gives a non-breaking three dots, and I always insert a space each side of it. The well-regarded and much-used Chicago Manual of Style recommends the use of an ellipsis for any omitted word, phrase, line or paragraph from within—but not at the end of—a block of text, and their preferred method of construction is three spaced periods.
