If I were named San, and somebody wanted to write out my name with the san honorific, what would it look like? A fiend of mine wants to name a plant San-san, but written correctly.

Given as how a Japanese person is unlikely to be named "San", the name itself should be written in Katakana. The "-san" honorific is always written in Hiragana. Therefore:

> ****
> **San** -san
