ไม่ได้

Explanation

ไม่ได้ combines the negator ไม่ with ได้, but its position relative to the main verb is crucial. ไม่ได้ + verb denies that an action or situation actually occurred. ไม่ได้ไป means “didn't go” or “haven't gone.” The expression itself is not simply a past-tense marker; time comes from context or words such as เมื่อวาน, “yesterday.” It is also commonly used to correct an assumption, as in ไม่ได้โกรธ, “I'm not angry.” Verb + ไม่ได้ says that the action cannot be carried out. ไปไม่ได้ means “can't go,” while ใช้ไม่ได้ means “can't be used.” The obstacle may be lack of ability, circumstances, health, the condition of an object, or a rule. When ได้ is the main verb “get” or “receive,” as in ไม่ได้เงิน, the phrase means that the following object was not obtained or received.

Usage

It is extremely common in both conversation and writing. Use it to deny a past or assumed action, correct a misunderstanding, state that circumstances or ability make something impossible, decline an invitation or request, or indicate that rules do not allow something.

Caution

Word order changes the meaning: ไม่ได้ไป means “didn't go,” while ไปไม่ได้ means “can't go.” The reason behind verb + ไม่ได้ must be inferred from context. กินไม่ได้ might mean that someone cannot eat it for health reasons, that it is inedible, or that eating it is forbidden. Add the reason when ambiguity matters. Said sharply on its own, ไม่ได้ can sound like a firm or commanding “No!”
