In standard English, for example, you can say I am or it is, but not “I am” or “it is.” This is because the grammar of the language requires that the verb and its subject coincide personally. The pronouns I and him are respectively the first and third person, just as the verbs are and are. The verbage form must be chosen in such a way as to have the same person as the subject, unlike the fictitious agreement based on meaning.   In American English, for example, the expression of the United Nations is treated as singular for the purposes of concordance, although it is formally plural. Remember: here are constructions, search for the subject AFTER the verb and choose a singular or plural verb to agree with the subject. The rule of thumb. A singular subject (she, Bill, auto) takes a singular verb (is, goes, shines), while a plural subject takes on a plural verb. SUBJECT-VERBE RULE #1 Two or more singular (or plural) subjects that are linked by a pluralistic composite subject and act as subjects of plural compound and adopt a plural (singular – singular – plural). 6.
Collective nouns (group, jury, crowd, team, etc.) can be singular or plural depending on their importance. The ability to find the right topic and verb will help you correct the errors of the subject verb agreement. Exceptions: fraction or percentage can be singular or plural, based on the following noun. Expressions of rupture like half, part of, a percentage of, the majority of are sometimes singular and sometimes plural, depending on the meaning. (The same is true, of course, when all, all, more, most and some act as subjects.) The totals and products of mathematical processes are expressed in singular and require singular verbs. The phrase “more than one” (weirdly) takes on a singular verb: “More than one student has tried to do so.” The rules of the subject verb agreement apply to all personal pronouns, except me and you, which, although SINGULAIRE, require plural forms of verbs. In Hungarian, verbs have a polypersonal concordance, which means that they correspond to more than one of the arguments of the verb: not only its subject, but also its object (accusative). There is a difference between the case where a particular object is present and the case where the object is indeterminate or if there is no object at all. (Adverbs have no influence on the form of the verb.) Examples: Szeretek (I love someone or something indeterminate), szeretem (I love him, she, or her, or her, specifically), szeretlek (I love you); szeret (he loves me, me, you, someone or something indeterminate), szereti (he loves him, her or her especially).
