I am not sure what "not use word of God" means. But as for "kosher" definition - it is closely translated as "fit for use". There are laws that
make certain food - kosher (meaning it is eatible for religious Jew) or taref (not usable, though direct translation is different).
For example, only meat of non-carnivorous beasts is allowed, if they chew their grass in certain manner (like cow) and have a certain design of
hoove.
This is what Torah says, now naturally during the ages certain new rabbinical laws also were added, somewhat different in different groups.
Judaism laws and food:

Also word "kosher" can be used to describe other things - not nessesary food - religious Jew can use : like kosher internet , kosher cellular phones
and other things. I do not know if ATS is kosher.
Hope it helps, if not - maybe i did not understand you correctly.
Edit:
Oh, maybe you mean why name of God (YHWH) is not spoken? Then i heard two versions (there might be more) - one is it is sign of respect. Other that it
basically "turns on" - allegorically - aspect of God that is responsible for judgement (or something similar, do not remember) and it is better not
to use it for common people. This is naturally more mystical approach.
