What is an ellipsis and how do you use one correctly?

An Ellipsis is three spaced periods that denote deleted text from a verbatim quotation (Hacker 270). The sentence should not differ in meaning, and should not be ill grammared (Hult 885).

Proper Use

As a simple tell to deleted text, the ellipses is used this way: Ziggy explained his magic trick by instructing to "multiply your age in years by 365.25 . . . that is your age in days."
To show that an entire sentence was deleted: "But mom," Chris pined,"I still have an hour left. . . . I won't be late for school."
- Note the use of the period before the ellipsis.
If showing hesitation or interruption an ellipsis may be used.
A line of dots is used when a line of text in poetry has been removed (Hacker 271).
If author being quoted has used ellipsis, quoter should use brackets around newly inserted ellipsis, to avoid confusion (Hult 886).
When omitting one or more entire paragraphs, indicate the omission by indenting four points and placing them on a separate line. Practice of that can be found in point 5 of the linked page.

Errors In Use

Using ellipsis to start or end a quotation is not needed. It is understood that the material is derived from a longer passage (Hacker 271).
- This rule is excused if the ellipsis is replacing the last quoted sentence; as required by MLA formatting (Hacker 271).
- When ending a quoted sentence with an ellipsis, use a fourth period as the end of the sentence (Hult 885).
Hodges warns: "Whenever you omit anything from material you quote, make sure your omission does not change the meaning of the original."
Using brackets around ellipsis only applies to quotations, not statements of your own (Hult 886).
Be careful not to overuse ellipsis, even in your own work, warns Hult.
An ellipsis should not have hanging periods. It should be one entity on the same line, as pointed out in idea six.
