"Matching up singular or plural subjects with singular or plural forms of a verb is part of the process called agreement. This is easy in simple sentences:
He admits that he is worried. [singular subject and verb]
They admit that they are worried. [plural subject and verb]
But there are some cases where the grammar is not so straightforward."
