Doubt on the infinitive usage

Question

I've been recently studying the verb patterns with which we use the infinitive and the -ing form (e.g. I suggest meeting tomorrow at my house, NOT: I suggest to meet tomorrow at my house).

But later, I came across this situation: I hope you to have a great time on Saturday. I hope you have a great time on Saturday.

I put these two sentences on Grammarly, and it told me that the "to" in the first one shouldn't be there. It's quirky for me since, in my textbook (which teaches British English), "hope" is among the verbs that must go with an infinitive.

Just in case you need to know, my Grammarly account is set to revise British English.

Thank you very much.

Answer 1

The following website points out that when we use hope for the future, we use "to" plus infinitive only when the subjects of the main and subordinate clauses are the same.

Perfect English Grammar how to use hope

We can use 'to + infinitive' with 'hope' for the future. When we use 'to + infinitive', the subject is the same as the subject of 'hope'.
I hope to come to the party tomorrow. (= I hope I can come to the party tomorrow.)
I hope to run a marathon this year.

In your example,

I hope you have a great time on Saturday.

the subject of hope is I, but the subject of have is you. In the case of different subjects in the main and subordinate clauses, we can use simple present tense to represent the future.
So "hope you to have" is not correct.
