Ellipsis
There are different ways to handle the ellipsis. Some of these are affected by using the insert symbol feature in a word processor. One common way to handle the ellipsis is with no spaces between the periods and a space on each side of the ellipsis when it is between words and no space between the ellipsis and a quotation mark.

Stylistically, ellipses are best used to give a thoughtful, contemplative feel to prose. They do not always have to be part of a quotation and can be used in narrative. While ellipses can serve a purpose, they should be used sparingly and not overused.

Usage
1. An ellipsis takes the place of omitted words in a quotation

Example: “She was talking about dresses, skirts, pants … until she turned blue in the face.”

2. To indicate a long thoughtful pause

Example: I wanted to call her … no, needed to call her.

3. Indicates trailing off (as opposed to an abrupt interruption)

Example: I couldn’t hike any farther. I just couldn’t do it anymore. Just couldn’t …

4. To indicate a continuation of time

Example: The timer counted down: ten, nine, eight …

5. To indicate pauses in conversation as if a “realization” is occurring

Example:”Why would he … would they?”
