The two places where subjects and verbs are most often at odds are numerous and tense. If the subject is plural, then the verb must also be plural. Similarly, if the subject is plural, then the verb must also be plural. It sounds like a no-brain, but things can get complicated when you talk about money, time, collective names, indeterminate pronouns, and interruption phrases. Although a plural verb is used when referring to individual dollar notes or coins, we generally do not refer to individual time units because time is abstract. Therefore, singular verbs are always used in place of plural verbs when a scribe refers to a period or unit of measurement. If the subject matter was plural, the verbs would have to change shape to agree with the subject. Add to the third person a singular form of regular verbs that end in -sh, -x, -ch and -s. (I wish/He wishes, I fix/you fixed, I observe/He observes, I kiss/He kisses.) The subject-verb agreement describes the correct correspondence between subjects and verbs. Not all verbs follow a predictable pattern. These verbs are called irregular verbs. Some of the most common irregular verbs are, have and do.
Learn the forms of these verbs in contemporary form to avoid errors in the subject-verb chord. The verb has three forms in the contemporary form: is, is, is, are. Use is whether the subject is a single name or a third-person-singularpronoun (him, she, it): If you have difficulty identifying the subject and the verb in sentences that start here or there; it can help reverse the order of the sentence so that the subject comes first. If you have difficulty finding the subject and the verb, you cross or ignore sentences and clauses beginning with prepositions or dependent words. The subject of a sentence will never be in a prepositional sentence or dependent clause. You may come across sentences in which the subject comes according to the verb rather than in front of the verb. In other words, the object of the sentence may not appear where you expect it to be. To ensure a correct match between the subject and the subject, you need to correctly identify the subject and the verb.
