After certain verbs, you use to + the base form of the verb (the infinitive). Here are the most common ones:

The Negative: not to
To make the infinitive negative, put not before to:

Dare
After dare you can use the infinitive with or without to:
- I didn’t dare to ask for a raise. or I didn’t dare ask for a raise.
But after dare not (or daren’t), drop the to:

daren’t to tell)
Seem, Appear, Pretend, Claim
These four verbs also take to + infinitive:

You can also use to be + -ing (continuous infinitive) and to have + past participle (perfect infinitive):

| to have + past participle | I seem to have lost the client’s file. | It seems that I have lost it. |
| not to have + past participle | She claimed not to have seen the memo. | She claimed that she hadn’t seen it. |
Question Words + to
After some verbs, you can use a question word (what / how / where / whether) + to + infinitive:
| Verb | Example |
|---|---|
| ask | We asked how to get to the conference centre. |
| decide | Have you decided where to hold the meeting? |
| know | I don’t know whether to apply for the position or not. |
| understand | Do you understand what to do with the new system? |
| remember | I can’t remember how to reset the password. |

You can also use show / tell / ask / advise / teach + somebody + question word + to:

Don’t Mix Up: to vs. -ing
Some verbs take -ing, not to. Watch out for these:
| Verb + to (infinitive) | Verb + -ing |
|---|---|
| I decided to leave early. | I enjoy working from home. |
| She agreed to help. | He suggested meeting at noon. |
| We hope to finish on time. | Are you thinking of changing jobs? |
If you use the wrong form, the sentence is wrong: enjoy to work, suggest to meet, thinking to change.
