Agreement rules
- Singular subject -> singular verb (adds -s).
- Plural subject -> plural verb (no -s).
- With 'each', 'everyone', 'nobody', use a singular verb.
- Two subjects joined by 'and' usually take a plural verb.
Key idea
The verb must agree with its subject in number, even in longer sentences; words like 'everyone' take a singular verb.
Remember
Do not be confused by words between the subject and the verb.
