What is subject verb agreement
​

subject-verb agreement is when the subject and the verb must agree with each other in number (singular or plural). so if a subject is singular the verb must also be singular and vice versa.

Explanation:

if the subject is singular (dog) add an "s" to the verb (walks)

but if the subject is plural (dogs) don't add an "s" to the verb (walk)

example : the dog walks down the street / the dogs walk down the street
