Explanation:
"Ellipsis" is the name given to a series of dots that can sometimes appear in a text. Ellipsis have several different uses. They are often employed in order to omit words that are considered superfluous or that can be understood by looking at the context. In literature, these can also indicate that a character is pausing or that he is reluctant to complete an idea. Finally, ellipsis can be used when a character is implying, rather than stating, something.
