Ellipsis: Omitting Repeated Words
Level C1 · Advanced Structures
Ellipsis is the deliberate omission of words that are understood from context, usually to avoid repeating something already clear from what came before. Native speakers do this constantly, especially after auxiliary verbs and conjunctions, to sound more natural and less repetitive: She can swim and he can too (not he can swim too) — swim is omitted because it's already clear.
Common places ellipsis happens:
- After auxiliary verbs, in short answers and after so/neither/too: Are you coming? — I might (be coming). She hasn't finished, and neither has he (finished). I'd like to help, and I will (help).
- In coordinated clauses with a shared subject or verb, the repeated part is dropped: She ordered a coffee and [she] a croissant. He wanted to leave but [he] couldn't [leave].
- After comparatives and as/than, the repeated verb is often dropped: She earns more than he does (earn) is fuller, but She earns more than him drops does entirely, leaving just the pronoun.
- In infinitive clauses, to alone can stand for a whole omitted verb phrase: I didn't want to go, but I had to [go]. You don't have to come, but you can [come] if you want [to come].
The most common mistake is over-explaining by repeating the full verb phrase when a shorter, more natural form exists — She can speak French and he can speak French too sounds unnatural and repetitive to a native ear; the idiomatic version drops the repeated verb: She can speak French and he can too. A second mistake is dropping too much — leaving out words that are NOT actually recoverable from context, which creates a genuinely unclear or ungrammatical sentence.
Look for an auxiliary verb (can, will, have, do, be) standing alone at the end of a clause, or a bare to at the end of a sentence — both are signs that a longer verb phrase has been omitted because it repeats something already stated. Coordinating conjunctions (and, but, or) joining two clauses with an identical subject or verb are also common ellipsis sites.
