Inherent vowel
The names of Thai letters show how inherent vowels are used. In Thai, each letter's name has at least two syllables, with the first being the consonant with the inherent vowel and the second syllable being the word where the consonant is used. The letter ก is named ก ไก่, or gaw gài. The letter itself, the first syllable, is always pronounced with -aw after the consonant.
