Modern English is not very consistent, although it exists. In the following sentences, pronouns and their predecessors correspond to the number, because they are both singular: conformity to the casus is not an essential characteristic of English (only personal pronouns and pronouns that have a casus marker). The concordance between these pronouns can sometimes be observed: • When the subjects are related by or by, nor, etc., the verb corresponds to the near subject. (Proximity rule)  Note: In this example, the subject of the sentence is even; That is why the verb must correspond to this. (Because scissors are the subject of the preposition, scissors do not affect the number of verbs.) Compared to English, Latin is an example of a very volatile language. The consequences for the agreement are therefore: Swahili, like all other Bantu languages, has many classes of names. In class, verbs must correspond to their subjects and objects, and adjectives to the subjects who qualify them. In the example above, the plural corresponds to the actors of the subject. In the very simple example above, it is clear that the subject is Singular and the subject It is plural.
And it is clear that the verb is consistent in all cases. But in some sentences, it`s not always that simple. The following guidelines will help you decide how to match a verb to its subject. Also note the concordance that is shown to be even in the subjunctive atmosphere. The predicate corresponds in number to the subject and if it is copulative (i.e. composed of a subject/adjective and a connecting verb), both parts correspond to the subject. .
