He offered to lend the book to the student.
Subject: He
Verb: offered
I don't know what the object should be, is it "to lend the book"? but then the object itself would be comprised of a verb and its complement, which makes it S+V+O+V+C , but this structure seems ungrammatical, what's the correct way to put this?
And what does the PP to the student stand for? I know it adds information to the verb lend , but is it a complement or something else?
He wants us to use the service.
Subject : He
Verb : wants
Object : us
"to use the service " confuses me, is it a complement consisting of infinitive verb + its complement or object?
But then the structure would look like S+V+O+C+V+C(or O), which doesn't seem grammatical, what's the correct way to explain this?
