Ellipsis happens when we leave out (in other words, when we don’t use) items which we would normally expect to use in a sentence if we followed the grammatical rules. The following examples show ellipsis. The items left out are in brackets [ ]: 1. I am absolutely sure [that] I have met her somewhere before. 2. [Have you] Seen my gloves anywhere? 3. She sang and [she] played the violin at the same time. 4. [Are] You ready yet? In fact, when we use ellipsis appropriately, no one thinks we have ‘left out’ anything, and ellipsis is normal and very common, especially in informal conversation
