About Thai
Thai is spoken by over 60 million people and is the official language of Thailand. It is a tonal language with five tones and uses its own unique script.

No spaces between words
Thai is written without spaces separating words. Spaces mark the ends of clauses and sentences instead, so a line of Thai is a continuous run of characters and the reader segments it themselves.
This is the first genuine obstacle, and it is a real one for dictionary use: before you can look a word up you have to work out where it starts and ends. It becomes automatic with exposure, but early on it is slower than learning the letters.
Five tones, and the mark does not tell you which
Thai has five tones — mid, low, falling, high and rising — and four tone marks. The mismatch is a warning: the mark alone never determines the tone.
Tone is computed from several things at once: the class of the initial consonant (mid, high or low), whether the syllable ends in a stop, the vowel length, and any tone mark present. The same mark on two different words produces two different tones. This is why Thai reading requires knowing the class of every consonant, and why learning a letter as merely "m" rather than "m, low class" leaves you unable to read tone.
The classic set: มา (maa, mid) is to come, หมา (mǎa, rising) is a dog, ม้า (máa, high) is a horse.
What is easier than expected
Thai grammar is comparatively light. No verb conjugation, no noun cases, no grammatical gender, no plural agreement, no articles. Tense is handled by context and time words rather than by changing the verb.
So the effort front-loads onto script and tone, and once those are in place progress is fast. Thai has around 60 million speakers and is the official language of Thailand.
Frequently Asked Questions
Why is Thai written without spaces?
Thai orthography uses spaces to mark clause and sentence boundaries rather than word boundaries, so text runs continuously and the reader segments it. It becomes automatic with practice, but early on it makes looking words up genuinely harder than learning the alphabet.
How do Thai tone marks work?
They are one input among several. Tone depends on the consonant class of the initial letter, whether the syllable ends in a stop, the vowel length, and any tone mark — so the same mark yields different tones on different words. Learning each consonant together with its class is essential.
Is Thai grammar difficult?
Less than the script suggests. There is no verb conjugation, no case, no gender and no plural agreement, and tense comes from context and time words. The difficulty is concentrated in writing and tone.
Can I get by with romanised Thai?
Only briefly. Thai romanisation does not represent tone consistently, so learners who stay with it tend to fossilise wrong tones. The script encodes tone systematically, which makes it the more reliable route despite the slower start.
