Put your hand in front of your mouth and say these English words:
That puff of air is called aspiration.
Thai treats aspirated and unaspirated sounds as completely different letters:
| Sound | Air | Thai Letter | Like English... |
|---|---|---|---|
| Unaspirated k | none | ก | sky |
| Aspirated k | puff | ข | kite |
You already know ก (from Lesson 1). Now meet its aspirated partner:
Each character has a memorable shape:
ข (egg) — Looks like ก with an extra loop. The extra loop = extra air!
ส (tiger) — Curvy S-shape, like tiger stripes.
ห (box) — Looks like a box. หีบ means "chest/box" — the shape matches!
Thai consonants sound different depending on position:
| Letter | Start of syllable | End of syllable |
|---|---|---|
| ข egg | kh (with air) | k (no release) |
| ส tiger | s | t (no release) |
| ห box | h | (not used) |
Here's something powerful: consonant class determines tone.
High-class consonants + simple vowel = rising tone ↗
Compare to middle-class ก (flat mid tone):
Same vowel, different consonant class = different tone!
You learned 3 high-class consonants:
| Char | Name | Sound | Remember |
|---|---|---|---|
| ข | egg (ไข่) | kh- | ก + loop = + air |
| ส | tiger (เสือ) | s- | S-curve shape |
| ห | box (หีบ) | h- | Looks like a box |
Key insight: High-class = aspirated (puff of air) + rising tone ↗
