What is subject verb agreement?



Hello, thank you for reaching out to us with this question.
Subject-verb agreement means that a subject and its verb must both be singular or plural. Let's use the examples you mentioned in your question:
1. The dogs (plural subject) runs (singular verb) in the park every morning - The subject and verb do not agree. According to the rules of the Present Simple tense, the plural subject 'dogs' must have a plural verb 'run'.
2. She and her friend (plural subject because they are two people) was (singular verb) late to the party - Once again the subject and verb do not agree. The plural subject 'She and her friend' must have a plural past tense verb 'were'.
I really hope that the explanation of these two examples helps you.
