Common Questions (6)

It is the standard word for 'not' in Thai. You use it to negate verbs and adjectives.
It goes immediately before the verb or adjective. For example: chan mai gin (I don't eat).
Not exactly. Mai chai is 'it is not.' If someone asks if you want food, you should use mai ao (don't want) or just mai.
You will be understood, but you'll sound like you're learning. Stick to mai for adjectives like 'beautiful' or 'big'.
No, it is specifically for commanding someone to stop an action.
No, use mai yak for that. ya is strictly for prohibiting others.
