Ellipsis

el‧lip‧sis plural ellipses

From the Ancient Greek: ἔλλειψις, élleipsis, ‘omission’ or ‘falling short’

There are two main meanings:

1. An ellipsis occurs when words are deliberately left out of a sentence, though the meaning can still be understood. For example, you can say ‘He’s going on holiday but I’m not’ instead of saying ‘He’s going on holiday but I’m not going on holiday.’
2. An ellipsis is the punctuation sign (…) used in writing to show that some words have deliberately been left out of a sentence. It is always three dots and some writers put spaces between the dots.
