Structure Concord (agreement between subject and verb) - SS2 English Lesson Note

Subject-verb agreement is the principle that the verb in a sentence must agree with the subject in terms of number (singular or plural). This means that if the subject is singular, the verb must also be singular; if the subject is plural, the verb must also be plural.

There are a few different ways to show subject-verb agreement. One way is to use the simple present tense. In the simple present tense, singular subjects take the verb form is or has, while plural subjects take the verb form are or have. For example:

Singular subject: The cat is sleeping.
Plural subject: The cats are sleeping.
Another way to show subject-verb agreement is to use the simple past tense. In the simple past tense, singular subjects take the verb form was or had, while plural subjects take the verb form were or had. For example:

Singular subject: The cat was sleeping.
Plural subject: The cats were sleeping.
There are also a few special cases of subject-verb agreement. For example, when the subject is a collective noun, the verb can be singular or plural, depending on whether the noun is referring to a group as a whole or to individual members of the group. For example:

Singular: The team is playing well. (The team is referring to the group as a whole.)
Plural: The team are playing well. (The team is referring to individual members of the group.)
Finally, there are a few irregular verbs that do not follow the regular rules of subject-verb agreement. For example, the verb to be has different forms for singular and plural subjects in the present tense:

Singular: I am.
Plural: We are.
Here are some more examples of subject-verb agreement:

Singular subject: The dog barks.
Plural subject: The dogs bark.
Singular subject: The woman is tall.
Plural subject: The women are tall.
Singular subject: The child is playing.
Plural subject: The children are playing.
