Object/subject question

Given the sentence:

I gave Tom a cup.

I can say, that

I is the subject.

But what is object here:

"Tom" or "a cup"

?

Answer

Denis, look up this article: "Ditransitive Verb". A ditransitive verb can have two objects, one direct, one indirect. They are also called primary and secondary.

In the sentence

I gave Tom a cup.

Cup is the direct object, and Tom, the indirect.
