G-d

G-d = G0d = God à la jewish way of writing it

The name of G-D is so holy to the Jewish faith that they dont even say the name or write it just on any document. That document might trivialy be tossed in the trash or left in vain. So a vigilance and mindfullness are maintained whenever G-d is the subject.

There are other people (atm no sure whom) that also have this kind of approach to their version of the creator. When they reffer to g-d they say He who's name is not to be uttered.
