Answer:
Ellipsis points, or "..."
Explanation:
These are used to show intentional omission from a statement or quote. Not only can they be used to show in dialogue that a character is "trailing off", but they also can show in a quote clip that the "important piece" has ended. It also informs the reader that the quote is just a snippet of the original statement, in order to avoid confusion and improve reliability.
Hope this helps!
