Hi, British Council!

I am confused with these use cases I read on some website:
"Gillian Flynn TO write female-led heist film for 12 Years a Slave director."
"Man likely TO sell 'dream house' because Comcast won't give him internet."
Could you help me? Thank you in advance.

Hello teachers.
You are not referring to the country or city, but to something in it.

Is it OK to use "to something" without a verb?

Hello Dwishiren,

Although it looks like part of an infinitive, 'to' here is actually a preposition and so it is fine to follow it with a noun. The verb in the second part of the sentence is the same as that in the first part, and it is omitted to avoid repetition:

You are not referring to the country or city, but (your are referring) to something in it.

Respected sir,

Please look at the sentence below

I am fortunate to have him as my friend.

Does the above 'to' infinitive work as a reason?

I means does it mean I am fortunate because I have a friend like him? Or does it mean something else?

Thank you.

Hello deepuips,

Yes, you are correct: it is is an example of an infinitive giving the reason for the adjective.

"Someone asked a clown......." In this sentence why don't we put "from". I mean in this way, "Someone asked from a clown"

Thank you.

Hello naaka,

That is not how the verb 'ask' works - it takes an object without any preposition. It might be helpful to look it up in our dictionary to see the example sentences there.

"He has no right to getting involved to it" Is this sentence grammatically correct? They used 'ing "form after "to".I know there are some sentences like that.for an example" I'm looking forward to helping you"And also I'd like to know how we can identify this thing.

Thank you.

Hello naaka,

I'll explain this, but just so you know, you can often find the answer to questions such as this one in our dictionary. If you look up 'right' there and look through all the entries (there are quite a few), you can see: in the right › [+ to infinitive] You have every right (= you have a good reason) to complain.

Therefore, 'He has no right to get involved in it' would be the correct way to say this. (Note also that the preposition that usually goes with 'involved' is 'in'.)
