Simple predicate? We had to banish Mel from the game because he was cheating.

Answer 1

There are two clauses here: the main clause and the subordinate clause ("because" and following).

Tell me what you think the two verbs are, and I'll check your work.

Answer 2

I believe that the simple predicate is "had" in the main clause.

In the subordinate clause... "was cheating".

What about "to banish"? is this an infinitive? Or an infinitive used as a direct object?

Answer 3

Your answers are right.
