The number of these words is influenced by a prepositional sentence between the subject and the verb. All the examples above show the match between the subject and the verb in the simple present tense. The concordance between the subject and the verb is also a problem in other forms of present. So far, we have worked with compound subjects whose individual parts are either singular or plural 2. If the different parts of the compound subject are connected by or not, use the verb (singular or plural) that corresponds to the subject closer to the verb. . . .
