Explanation

The basic order is subject + ไม่ + verb or descriptive predicate. Thai does not change the form of the predicate for negation; ไม่ is placed before the part being negated. To say that someone or something is not a noun, use ไม่ใช่ + noun. Common patterns include ยังไม่ “not yet,” ไม่เคย “have never,” ไม่ต้อง “do not need to,” ไม่ค่อย “not often/not very,” and ไม่...เลย “not at all.” In replies, ไม่ can stand alone, but repeating the verb after it is often clearer.

Usage

It is used in nearly every setting where negation is needed: denying facts, describing preferences or conditions, saying what someone will not do, and declining invitations or offers. For a polite refusal, speakers can add ครับ or ค่ะ, as in ไม่เอาครับ/ค่ะ.

Caution

For a prohibition meaning “don’t do it,” Thai normally uses อย่า, not ไม่: อย่าไป means “don’t go,” while ไม่ไป means “not going” or “won’t go.” Also, ไม่ได้ can mean either “cannot” or “did not,” so its interpretation depends on time expressions and context.
