> Does 'yuki' really mean happiness?
I feel like this is a loaded question, so let's break it down.
* The character means "happiness".
* If the name is written using this kanji, then it also means "happiness".
* by itself does not necessarily mean anything— and simply represent sounds.
* However, context could easily provide a meaning to those sounds, and as a word has several different meanings.
* If you knew someone named 'Yuki' who spelled it simply (or possibly ), it might not have any meaning.
* If you see someone's name written as , you'd be wise not to assume it's read as (or anything else).
