In this case, what form of a verb should be used? Should the verb be singular to agree with a word? Or should the verb be plural to agree with the other? 1. Group nouns can be considered as a single entity and therefore adopt a singular verb. A clause that begins with whom, what or what and between the subject and the verb can create problems of correspondence. 4. Think about the indefinite pronoun exception that is taken into account in section 3.5, p.18: some, all, none, all and most. The number of these words is influenced by a prepositional sentence between the subject and the verb. But if the subject is plural, then the verb must be plural. 2. If the different parts of the assembled subject are connected by or not, use the verb (singular or plural) that corresponds to the subject closer to the verb. .
