Ellipsis is a mark or series of marks that usually indicate an intentional omission of a word in the original text. An ellipsis can also be used to indicate a pause in speech, an unfinished thought, or, at the end of a sentence, a trailing off into silence (apostrophe and ellipsis mixed). When placed at the end of a sentence, the ellipsis can also inspire a feeling of melancholy longing.
