Ellipsis: infinitives
to used instead of whole infinitive: We hope to.
We can use to instead of the whole infinitive of a repeated verb (and following words), if the meaning is clear.
- ‘Are you and Gillian getting married?’ ‘We hope to.’
- ‘Let’s go for a walk.’ ‘I don’t want to.’
- I don’t dance much now, but I used to a lot.
- Sorry I shouted at you. I didn’t mean to.
- ‘Somebody ought to clean up the bathroom.’ ‘I’ll ask Jack to.’
Be and have (used for possession) are not usually dropped.
- There are more flowers than there used to be. (not
… than there used to.) - She hasn’t been promoted yet, but she ought to be. (not
… but she ought to.) - You’ve got more freckles than you used to have. (not
You’ve got more freckles than you used to.)
Ellipsis of whole infinitive: I’ll try.
In some cases the whole infinitive can be left out. This happens after nouns and adjectives.
- He’ll never leave home; he hasn’t got the courage (to).
- You can’t force him to leave home if he’s not ready (to).
It also happens after verbs which can stand alone without a following infinitive.
- ‘Can you start the car?’ ‘I’ll try (to).’
(would) like, want, etc
We cannot usually leave out to after would like/love/hate/prefer, want and choose.
- ‘Are you interested in working abroad?’ ‘I’d like to. ’ (not
… I’d like.) - My parents encouraged me to study art, but I didn’t want to. (not
… I didn’t want.)
However, to is often dropped after want, and almost always after like, when these are used after certain conjunctions – for instance when, if, what, as.
- Come when you want (to).
- I’ll do what I like.
- Stay as long as you like.
