Altaic languages
The three language families often united as the Altaic languages—Turkic, Mongolic, and Manchu-Tungus—are agglutinative. The largest languages are Turkish, Azerbaijani and Uzbek—all Turkic languages. Altaic inflection is, or is developed from, affixing. Grammatical markers directly added to the word perform the same function as prepositions in English. Almost all words are inflected according to their roles in the sentence: verbs, nouns, pronouns, numerals, adjectives, and some particles.
