Formal:
* Nimefurahi kukutana nawe. (Nee-meh-foo-rah-hee koo-koo-tah-nah nah-weh) - This is a direct translation of "I am happy to meet you."
* Nimefurahi sana kukutana nawe. (Nee-meh-foo-rah-hee sah-nah koo-koo-tah-nah nah-weh) - This is the same as the first option, but emphasizes the happiness and adds "very" for a stronger sentiment.
Informal:
* Nimefurahi kukutana nawe. (This is the same as the formal version but used in informal situations.)
* Nimefurahi kukujua. (Nee-meh-foo-rah-hee koo-koo-joo-ah) - This means "I'm happy to know you."
Even more informal:
* Samahani. (Sah-mah-hah-nee) - This is a more casual greeting, roughly equivalent to "nice to meet you." It can be used with friends or acquaintances.
You can also use a phrase like:
* Karibu. (Kah-ree-boo) - This means "welcome." It can be used to greet someone in a friendly way.
It's important to note that Swahili is a language with many nuances, so the best phrase to use will depend on the specific context and your relationship with the person you are speaking to.
