Subject-Verb Agreement

General Rule
The verb must concord or agree with the subject noun in respect of grammatical number.
(Singular verb for singular noun and plural verb for plural noun.)

Pancakes with syrup sound yummy.

Pancakes, while a filling breakfast, are messy!

Rule: The general rule for subject-verb agreement applies even when the verb is separated or divorced from its subject by a string of words.

Explanation: The verbs 'sound' and 'are' are not governed by the nouns next to them, but by the distantly located subject 'pancakes' (plural).

Everyone likes pancakes.

Rule: A singular verb is used with a singular indefinite pronoun.

Explanation: 'Everyone' is the singular indefinite pronoun.

Each of us gets three pancakes.

Rule: With 'each of ...' and a plural noun, a singular verb is preferred, a plural verb is informal.

Either juice or coffee goes with pancakes.

Neither you nor I like coffee.

Cereal or eggs are tasty.

Rule: When a mix of singular and plural nouns / pronouns are joined by 'or', the verb follows the preceding noun / pronoun.

Explanation: The verbs 'goes', 'like' and 'eggs' are governed by the nouns / pronoun closet to it.
