The infinitive without to is known as the BARE-INFINITIVE and is used after the special verbs will, would, shall, should, can, could, may, might & must. It is also used after need and dare when they are used as special verbs.
Tomorrow will be Sunday.
You can go now.
It might rain.
You should work harder.
Need I come again?
How dare you beat her?
The verbs MAKE and LET are followed by object + bare infinitive.
I made him give me the money back.
She let us use her phone.
Note, however, that the verbs force (or compel) and allow take the to-infinitive.
I forced him to give me the money back.
She allowed us to use her phone.
When used in the passive, make is followed by the to-infinitive.
He was made to give me the money back.
The verbs feel, hear, see, watch, notice, observe, listen can be used with object + bare infinitive.
I felt something touch my foot.

The verbs SEE & HEAR, when used in the passive, take the to-infinitive.

We can combine two sentences into one sentence using TOO + adjective + to-intinitive. The latter part is a kind of negative.
Dick is very weak.
Dick doesn’t lift the box.
Dick is too weak to lift the box.
Dick is very young.
She can’t go to school.

The coffee is very hot.
We can’t drink it.
The coffee is too hot to drink.
Note that the to-infinitive in the last example (“to drink”), though active in form, is passive in meaning. Here the action expressed by the to-infinitive is not performed by the subject of the main verb. In such cases, for + noun / pronoun can be placed before the to-infinitive.
The coffee is too hot (for us) to drink.

He can buy a car.
Mr. White is rich enough to buy a car.

The to-infinitive in the last example is passive in meaning. For + noun / pronoun may be introduced in such cases.

TOO & ENOUGH may also be used with adverbs.
