Concord and agreement are like the perfect pair in language; they ensure that the different elements in a sentence match and work harmoniously together. Just as a well-matched team achieves success, concord and agreement lead to grammatically correct and coherent sentences.
Singular Subject with Singular Verb:
When the subject of a sentence is singular, the verb must also be singular.

Plural Subject with Plural Verb:
When the subject of a sentence is plural, the verb must also be plural.

Singular Indefinite Pronoun with Singular Verb:
Singular indefinite pronouns, such as “everybody,” “someone,” or “nothing,” require singular verbs.

Collective Nouns with Singular or Plural Verbs:
Collective nouns, referring to a group of individuals, can take either a singular or plural verb depending on the context. If the group is seen as a single unit, a singular verb is used. If the focus is on individual members of the group, a plural verb is used.
