Tap the word to hear it. That's real premium audio from the HearThai Academy library — the same audio the app teaches with.
Why ไหน sounds the way it does
Thai tone isn't random — it's produced by four things working together in each syllable: the initial consonant's class, the vowel's length, whether the syllable ends live or dead, and any tone mark. Read the row, get the tone.
| Syllable | Class | Vowel | Ending | Mark | Tone |
|---|---|---|---|---|---|
| ไหน | HIGH | LONG | LIVE | — | RISING |

Common questions
How do you say which in Thai?
Which in Thai is ไหน, pronounced nǎi. Play the audio above to hear it spoken by a premium Thai voice — the tones are the part that spelling can't teach you.
What tones does ไหน use?
ไหน has 1 syllable: ไหน (nǎi) is rising tone.
Is the romanization nǎi enough to pronounce it?
No — and this is the trap most learners fall into. Romanization shows you the letters, not the pitch shape your voice has to make. Thai speakers hear the tone first. Use the spelling to recognize the word, and use the audio to learn it.
The short version
- ไหน (nǎi) means which.
- It has 1 syllable, carrying the rising tone.
- Its tone comes from the consonant class, vowel length, live/dead ending and tone mark — not from memorizing it word by word.
- Reading the romanization is not the same as hearing it. Play the clip until you can say it back without looking.
- One word is a start. Thai fluency is an ear that recognizes thousands — which is what HearThai Academy trains.
That's one word.
