Türkçe´de 8 sesli harf vardır ve 2 temel gruba ayrılırlar:

- Kalın sesli harfler: a, ı, o, u

- ince sesli harfler: e, i, ö, ü

Note for students: Turkish language is a phonetic language and therefore vowels become very important and you should remember this 8 vowels and their different classifications which we will study in due course.  Because in future lessons you will see that all the turkish ´endings´ will work together always following the vowel harmony rules.
