These 9 letters are the mid class consonants. Every mid-class letter's name starts on a plain mid tone: gaw, jaw, daw, dtaw. Two sounds here don't exist in English: ต dtaw is a hard, unaspiratedi t (between English t and d), and ป bpaw is the same idea for p. อ aw is special — it's a silent consonant that carries vowels, and doubles as the vowel sound aw.
Every Thai consonant has a two-part name: its sound plus a word that starts with it — like saying “A for Apple.” So ก is gaw gài: “gaw” is the sound, ไก่gài means chicken. Tap a card to hear the full name, or the pill to hear just the word.
