LONG VOWELS IN KYRGYZ LANGUAGE
Vowels in Altaic languages are categorized into two types as back vowels (thick) (a, aa, o, oo, u, uu, ı, ıı) and front vowels (thin) (e, ee, ö, öö, ü, üü, i, ii) (Poppe, 1960: 148). Long vowels in the contemporary Kyrgyz language (Kırg. suu, too etc.), appeared because of consonant assimilation. Primary long vowels no longer exist in the Kyrgyz language except for some cases (кырг. aarı, taanı etc.).
