Three "no": ไม่, ไม่ ใช่ and เปล่า

The negation of a verb or a quality is the particle ไม่ (mai, falling tone) before the word: ไม่ เข้าใจ — "don't understand", ไม่ ชอบ — "don't like". The verb does not change — Thai has nothing to conjugate. For example: “ไม่ เข้าใจ” — I don't understand. A rule from the Thai course: worked out on examples, not memorized as a wording.

How it works

The negation of a verb or a quality is the particle ไม่ (mai, falling tone) before the word: ไม่ เข้าใจ (май кхаочай) — "don't understand", ไม่ ชอบ (май чоп) — "don't like". The verb does not change — Thai has nothing to conjugate.

The negation of a noun or a fact is ไม่ ใช่ (mai chai), literally "not so": ไม่ ใช่ ร้าน กาแฟ (май чай ран кафэ) — "this is not a coffee shop".

And the colloquial third: เปล่า (plao) — a short "oh no, no" in reply to a question. To "have you eaten?" Thais more often say plao than any full form.

By example

  • ไม่ เข้าใจ
    май кхаочай
    I don't understand
  • ไม่ ใช่ ครับ
    май чай кхрап
    No (not so)
  • ไม่ ชอบ เบียร์
    май чоп бия
    I don't like beer

How the rule settles in your head

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
