Lesson 1: How Thai works

The big picture

  • Thai has its own alphabet: 44 consonants, around 32 vowel forms, and 4 tone marks.
  • It is written left to right, usually without spaces between words. Spaces mark the end of a phrase or sentence.
  • Vowels can appear before, after, above, or below the consonant they belong to.
  • Thai is tonal: the same syllable said with a different pitch is a different word.
  • Grammar is friendly: no verb conjugation, no plurals, no articles (a, the).

Romanization used in this course

Romanization is only a bridge to the Thai script. This course uses:

Symbol Sounds like Example
k, t, p unaspirated — like the k in “skip” (no puff of air) ไก่ kài (chicken)
kh, th, ph aspirated — like English k, t, p (with a puff). ph is never “f”, th is never “th” in “the” ไข่ khài (egg)
j between j and ch, unaspirated จาน jaan (plate)
ng ng in “sing”, can start a word งู nguu (snake)
doubled vowel aa, ii, uu… long vowel มา maa (come)
ue like oo with spread lips (no English equivalent) มือ muue (hand)
ɔ aw in “law” พ่อ phɔ̂ɔ (father)
ɛ a in “cat” แม่ mɛ̂ɛ (mother)
oe like u in “fur” เธอ thoe (you/she)

The 5 tones

Tone marks in the romanization show the pitch:

Tone Mark Pitch Example Meaning
Mid (none) flat, normal voice มา maa come
Low à flat, lower ใหม่ mài new
Falling â high, then drops ไม่ mâi not
High á high, slightly rising ม้า máa horse
Rising ǎ dips low, then rises หมา mǎa dog

Practice sentence: ไม้ใหม่ไม่ไหม้ไหม mái mài mâi mâi mǎi — “Doesn’t new wood burn?” Four nearly identical syllables, four different tones.

Exercise

Say each word five times, exaggerating the tone, then try them in a random order:

มา · หมา · ม้า · ไม่ · ใหม่
