In our language, some words focus only on nouns or subjunctive clauses, which give the word a grammatical meaning, add tone to them, reveal their implications and importance. This article describes the spelling of word classes in the Kazakh language, orthographic features of some conjunctions – homonymic series, difference from other parts of speech, correct spelling (together, separately), grammatical features, use in language, meaning in combination with preceding words. The external personality is similar to some ending words. We will only ask a question about the word that comes before it. For example, this year I am also writing a dissertation (who is writing a diploma – I am?). – I have a very interesting book called «From childhood to Wisdom». (Who has the book? – I have). The locative case has endings (да, де, та, те – and, both… and, as well as, not only, but also) with coordinating conjunctions the location of a person or object, interrogative conjunctions-particles (ма, ме, ба, бе, па, пе – if, really, is, really) with this personal negative suffix phrase: the lexical-semantic character and grammatical features of the ending words were considered in comparison with the suffix, so as not to confuse the instrumental cases either (мен, бен – so, within ) with the coordinating conjunctions. It is proved by examples that if you answer these questions, the suffix will be written together with the same word. And in which case there will be a conjunction, the general meaning of the sentence will not be violated, although the conjunction will be lowered, it was considered with concrete data and evidence. A number of words used in the negative sense are also revealed, as well as the differences, features and spelling of coordinating conjunctions – particles (ма, ме, ба, бе, па, пе – if, whether, really) at the end of an interrogative sentence.
