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). Of course, names or pronouns can specify the exact object. In short, there is agreement between a verb and the person and the number of its subject and the specificity of its object (which often refers more or less precisely to the person). Languages cannot have a conventional agreement at all, as in Japanese or Malay; barely one, as in English; a small amount, as in spoken French; a moderate amount, such as in Greek or Latin; or a large quantity, as in Swahili. The use of case morphology and agreement for children offers a window on the structure of their developing grammatical systems. Children who acquire English often produce accusative pronouns in position and use forms of verbs without concordance morphology. Systematic patterns of these errors and the links between them have been the subject of much research in recent decades. This chapter presents some of the theoretical results and interpretations as well as discussion points on methodology.
The discussion focuses on English, taking into account other languages in which predictions are different, and the topics include a general overview of the relationship between case and agreement, option/root-infinity, standard case and morphological access. Indeed, noun modifiers in languages such as German and Latin coincide with their subtantives in numbers, sex and cases; The three categories are mixed into declination paradigms. The adjectives correspond in terms of sex and number with the nouns they change into French. As with verbs, chords are sometimes displayed only in spelling, as forms written with different modes of concordance are sometimes pronounced in the same way (z.B pretty, pretty); Although, in many cases, the final consonan is pronounced in female forms, but mute in male forms (z.B. small vs. small). Most plural forms end in -s, but this consonant is pronounced only in contexts of connection, and these are determinants that help to understand whether it is the singular or the plural. In some cases, the entries of the verbs correspond to the subject or object. The agreement generally includes the matching of the value of a grammatical category between different elements of a sentence (or sometimes between sentences, as in some cases where a pronoun agrees with its predecessor or its reference opinion).
Some categories that often trigger grammatical chords are listed below. In Nynorsk, Norway, Swedish, Icelandic and Norway, current participants must agree on gender, number and certainty whether the participatory party is in an attribute or predictive position. With regard to the Icelandic and the fist table, the current participants should also agree in the grammatical case. At the beginning of modern times, there was an agreement for the second person, which singularus all the verbs in the current form, as well as in the past some usual verbs. It was usually in the shape-east, but -st and t also occurred.
