Grammar is nothing more than a way to combine words into sentences. Below are a couple rules for grammar that one should remember.
SUBJECT AND VERB AGREEMENT
- A basic rule of English is a verb must agree with its subject in number. A
singular subject needs a singular verb; a plural subject needs a plural verb.
As an example:
We (a plural subject) are (a plural verb) the best employees.
- Use a plural verb when and is used to join two or more subjects. Example:
The manager and the lead are working on . . . .
- But, if two or more singular subjects are joined by or or nor, use a singular
Susan or John is available for the project.

NOUN AND PRONOUN AGREEMENT
A pronoun must agree with its antecedent (the word for which the pronoun stands) in number, gender, and person. Some examples:
Susan said she could handle the job alone.
We must stand by our position, just as you must stand by yours.
The department filed its report.
