Grammar Rule in 30 Seconds

Use 'Haam' before a verb to strictly forbid an action, often seen on signs or in formal warnings.

  • Place 'Haam' directly before the verb: 'Haam' + Verb.
  • It is inherently formal and authoritative, not for casual requests.
  • Do not use 'Mai' (no) with 'Haam'; 'Haam' already carries the negative force.
🚫 + ห้าม (Haam) + Verb

Pronúncia

hâam

Tone

Haam has a falling tone. Start high, then drop.

Authoritative

ห้ามเข้า! (Downwards)

Strict command

Memorize It

Mnemonic

Haam sounds like 'Harm'. If you do it, you cause harm, so it is forbidden.

Visual Association

Rhyme

When the sign says Haam, keep your cool and stay calm.

Story

I walked into a park. I saw a sign saying 'Haam'. I tried to enter, but a guard stopped me. I realized 'Haam' means I cannot go in.

Word Web

ห้ามเข้าจอดสูบถ่ายทิ้งใช้

Desafio

Find 3 'No' signs in your city and translate them into Thai using 'Haam'.

Notas culturais

Thais value harmony. Using 'Haam' directly can be seen as aggressive, so it is often softened with 'na' or used only in official contexts.

Derived from the verb 'to forbid' in Proto-Tai.

Perguntas frequentes (8)

Only if you are setting a serious boundary. Otherwise, it sounds like you are scolding them.

No. Mai is for general negation, Haam is for prohibition.

It is grammatically redundant. Haam already contains the negative force.

Haam is for rules/authority; Ya is for advice/requests.

No, it is a command, not a question.

Add 'na' at the end or use a polite particle like 'krub' or 'ka'.

No, it is for future or ongoing prohibitions.

Always directly before the verb.
