What this grammar point covers
An infinitive in English is the base form of a verb, usually with 'to' in front. For example, 'to eat', 'to go', or 'to study'. Infinitives are used in many ways, like after certain verbs, adjectives, or to show purpose.
When to use it
Use infinitives after certain verbs (like 'want', 'hope'), after adjectives, to explain why someone does something (purpose), or as the subject of a sentence.
Key forms
- 'to' + base verb (to eat, to go, to study)
- Negative infinitive: 'not to' + base verb (not to eat)
Examples
She decided to travel.
It is important to listen.
They came to help.
Tips
- Do not use 'to' with modal verbs (say 'can go', not 'can to go').
- Some verbs are followed by an infinitive, while others need the -ing form. Check which is correct.
- Remember: 'to' + verb, not 'to' + 'to' + verb.
Exceptions and edge cases
- After some verbs like 'make' and 'let', use the base verb without 'to' (e.g., 'She made me do it.').
- Some verbs can be followed by either infinitive or -ing with a change in meaning (e.g., 'stop to eat' vs. 'stop eating').
