Subject/Verb Agreement

 

The rules of Subject-Verb Agreement are about the use of S-endings on either the subject or verb (but not both). Here below are the example of Subject-Verb Agreement. For your information, in each sentence, the group of (black) bold word(s) is the subject and the group of remaining word(s) is the predicate. Also, it is the key word that decides if the verb adds "-s" or not. This key word is in maroon (bold) and all verbs and helping verbs are underlined.
