Here are some other ways to say no, depending on the context:
* "Si" - This is a more emphatic "no", similar to "not at all" in English.
* "Hapana kabisa" - This means "no at all" or "absolutely not".
* "Samahani" - This means "sorry", and can be used to politely decline an offer.
Remember that context and tone are very important in communication. The way you say "no" will depend on your relationship with the person you are speaking to, and the situation.
