Basics & Tonality — The 5 Tones

Thai belongs to the Tai-Kadai language family and is a tonal language: The same word can have five completely different meanings depending on the tone. The most famous example:

"Mai" — one word, five meanings:

Tone	Phonetic	Thai	Meaning
Middle	mai	ไม	Mile / Wood
Low	mài	ไม่	not / no
Falling	mâi	ไม้	Stick, Wood
High	mái	ไหม	Silk / Question particle
Rising	mǎi	ใหม่	new

The Five Tones

• Middle Tone (สามัญ): Neutral, steady pitch — like a normal German declarative sentence.
• Low Tone (เอก): Starts low and stays low. Like a tired, resigned sigh.
• Falling Tone (โท): Starts high and falls. Like a firm German "No!" (from high to low).
• High Tone (ตรี): Starts high and stays high. Like a surprised question: "Really?!"
• Rising Tone (จัตวา): Starts low and rises. Like the German question intonation: "Really?"

Further Basic Rules

• Gender: Men end polite sentences with "kráp" (ครับ), women with "kâ" (ค่ะ). This is not optional — omitting it seems rude.
• No Plural: Thai has no plural endings. "Dog" and "Dogs" are the same word.
• No Conjugation: Verbs are not inflected — tenses are expressed through context words.
• Thai Script: 44 consonants, 32 vowels, no spaces between words. You don't need to learn it for a short vacation.
