I need help with this sentence in Swahili?

Question

My teacher wrote this sentence in Swahili i think in my yearbook.
Does anybody know what it means?
Asante Tsana Rafiki Yango Mtoto Mzuki Tsana.

I learned asante is thanks and rafiki is friend.
But anyways please tell me what it stands for in english!
Thanks!

Answer 1

Can't find many of the words in my online dictionary
as written. But I can make a guess.
I think "tsana" should be "sana".
Then asante sana means thank you very much.
Yango should be yangu = my
Rafiki yangu = my friend.
Mtoto is a child.
Mzuki might be mzuri which means "good".
So mtoto mzuri sana = a very good child.
So a plausible translation is
Thank you very much my friend, a very good child.
Just my guess though!
