what does the word Kaz mean?

I'm just guessing that maybe you are referring to a male name "Kaz," or "Kazu," which is normally an abbreviated version (nickname) of longer names such as "Kazuo," "Kazuhiro," "Kazuhiko," "Kazutoshi," etc., etc., there are many male names that start with "kazu-." And often they drop the last "-u" to make it easier for English speakers to remember and pronounce.

From the sound alone, you cannot really tell the meaning of Japanese words. It's kanji that has meanings; there are more than one kanji that can be pronounced "kazu," so unless you know the kanji, you cannot tell. ... Are you asking about a name? :)

Well yes. One of our baseball players is named Kaz (Matsui) and I like the sound of it so I was curious as to it's english translation.

Kazuo Matsui, the one in Colorado Rockies? His nickname is Kaz, and his full first name is Kazuo. It is written (as professional) ‰Ò“ª‰›, consisting of three kanji, each of which meaning "earn," "head," and "center." But his *real* name (as given by his parents) is written ˜a•v, consisting of two kanji, meaning "harmony" and "male/husband."

Yes that's the one. He is an awesome ball player and I like him very much. Thank you for your help! This might seem funny but I have a new kitten and I like to name my animals with a not so common name, so I will name him Kaz because he does bring "harmony" into my life.
Thanks again! This really helped me and I appreciate your efforts.
