The other main reason is that the subject-verb agreement in English is almost always a purely formal matter, in the sense that the question of whether or not the verb corresponds to the subject does not influence the interpretation of the sentence in which the subject and verb in question are located. If you can replace the word they with the compound subject, the sentence takes the plural form of the third person. First, the rule makes it seem that each verb has a singular form used with all singular subjects and a plural form used with all plural subjects. It`s not true. If we do not take into account the verb be and modal tools, all verbs have a form that is used in the third person singular, that is, with the pronouns he, she and it, and with subjects that could be replaced by one of these three pronouns, as in example (1) below, and a form that is used with all other subjects. == singular first and second person materials (2) and all types of plural materials (3): 1. If the subject of a sentence consists of two or more nouns or pronouns that are by and connected, use plural verblage. If you have trouble finding the subject and verb, delete or ignore sentences and clauses that begin with prepositions or dependent words. The subject of a sentence will never be included in a prepositional sentence or in a dependent clause. RULE2: The number of the subject (singular or plural) is not changed by words (or a sentence) that lie between the subject and the verb. Example: one of the boxes is opened.
Here is the subject “one” and the verb “is” both singularly. 3. If a compound subject contains both a singular and plural noun or a pronoun connected by or by or nor, the verb must correspond to the part of the subject closer to the verb. Example: Information received from business owners was relevant to be included in the study. The indeterminate pronoun all takes a plural form, because all refer to the plural people. Because people are plural, everything is plural. If you are looking for an exception to the statement that subject-verb concordance has no influence on interpretation, try using a plural zero subject, for example. B sheep. . .
