Article 10. The word has been replaced by phrases that express a desire or that go against the fact: singular subjects need singular verbs, while plural subjects need plurals. The verbs “be” change the most depending on the number and person of the subject. Other verbs do not change much on the basis of subjects other than the verbs of the simple form of the present. If the subjects are a singular number of a third person, the verbs are used with s/s when they are in a simple present form. The verbs with s/es in the sentence are called singular verbs. It is recommended to rewrite these sentences whenever possible. The previous sentence would be even better than: 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 chord or concord (in abbreviated agr) occurs when a word changes shape according to the other words to which it refers.  This is a case of bending and usually involves making the value of a grammatical category (such as sex or person) “agree” between different words or parts of the sentence. The subject of a sentence must always correspond to the verb that describes its action. This helps your reader understand who or what is doing something and makes your writing easier to read.
Apart from verbs, the main examples are the determinants “this” and “that” which become “these” or “the” if the following noun is plural: the predicate is in number consistent with the subject and if it is copulatory (i.e. composed of a noun/adjective and a link), the two parts correspond in number to the subject. For example: A k-nyvek ardek voltak “Books were interesting” (a: this: “k-nyv”: book, “erkes”: interesting, “voltak”: were): the plural is marked on the theme as well as on the addjectival and the copulatory part of the predicate. Sometimes the subject follows the verb, especially when the sentence begins here or there. In this case, there is no subject – the real subject must be identified and compared to the correct form of verb. Often, the verb does not directly follow the subject, which can lead to contractual errors. Make sure the verb matches the right subject, especially in long sentences with sentences or clauses between the subject and the verb.
