แน่นอน
nɛ̂ɛ-nɔɔn/nɛː˥˩.nɔːn˧/
The English word "sure" can be translated into Thai as แน่นอน (nɛ̂ɛ-nɔɔn).
แน่นอน is used to express that something is certain or to say "certainly" or "for sure". It can function as an adverb, often placed at the end of a sentence.
Meaning: certain in one's knowledge or belief (adj)
Which one should you use?
While แน่นอน is the standard way to express certainty, the related form แน่ใจ is specifically used to express the feeling of being sure or certain about something. In casual conversation, the loanword ชัวร์ is also used to mean sure or certain.
How do you pronounce it?
The romanization is nɛ̂ɛ-nɔɔn.
Did you know?
- If a Thai speaker says ไม่แน่ (not sure), they are often not just expressing doubt, but politely signaling that a request might be impossible to fulfill.
- While แน่นอน means 'certain', the word นอน used in its construction literally means 'to sleep' or 'to lie down' in other contexts.
- Thai speakers often use the particle นะ after แน่นอน to soften the tone, turning a blunt statement of fact into a more persuasive or gentle assurance.
