common features
turkic languages generally share the following features
vowel harmony: this is common in many agglutinative languages. it means that vowels assimilate, meaning that the vowels of affixes will change according to the vowels of the stem/"main word", based on certain articulation features (for example, where the vowels are produced (front, back, high, low), and how they are pronounced (tongue position, rounding of lips)).
agglutination: this means that words are made of morphemes, which each carry a syntactic feature.
