VERBS OF ENABLEMENT AND OBLIGATION IN ENGLISH
allow, ask, authorise, instruct, invite, leave, oblige, permit, require, tell, want etc
After these verbs, the second verb is in the infinitive with to.

The man instructed me to come down.
The police required me to give a blood sample.
I want you to know I love you.
for example, we cannot say:
** The man permitted to open the doors **All the verbs listed can be easily used in the passive except want.
** I told not to do that **
The singer was told to come down.
He was invited to give a concert.
She was forbidden to leave the room.

These verbs are followed by “from” and an -ing structure. The word “from” is essential with hinder, optional with stop and prevent.
He hindered us from starting in time.“Stop” is not usually used in the passive, but hinder and prevent easily accept passive structures:
He stopped me (from) falling in the hole.
They prevented me (from) going out.

The verb forbid is followed by a full infinitive with to, just like verbs of obligation above. It can also be used in the passive

Of these three verbs, only let can be used as a consecutive verb, i.e. followed directly by a second verb.
Make and tell must always be followed by a noun or pronoun complement.

Don’t confuse let and leave: when followed by an object and a subsidiary clause, leave means abandon, quit.
