Agreement is what it sounds like—matching. Specifically, agreement refers to the matching of number, person, and gender within a sentence. Subjects and verbs must match in number (singular or plural) and person (first, second, or third). Pronouns and their antecedents (the words to which they refer) must also match in gender (masculine, feminine, or neuter). The following reviews the person, number and gender:
• Singular- I am here
Plural- We are here
• Singular- I was here
Plural- We were here
• Singular- I begin
Plural- We begin
Those spoken to:

Singular- It is here Plural- They are here
Singular- He(She) was here Plural- They were here

Sentences that do not maintain agreement among all their elements sound clumsy; they can be ambiguous as well. Sentences in which all the parts do agree help make your point more clearly and logically. There are several situations that can cause difficulty with agreement.
A subject must agree with its verb in number.
A singular subject takes a singular verb. A plural subject takes a plural verb.
