YHWH is the name of the Jewish god, who claimed to be Elohim (or El), the previous word of god.

The pronounciation of YHWH was apparently kept secret by the high priests and was eventually lost. Nobody knows how it was originally pronounced.

Some have suggested YaHWeH, others say JeHoVaH, but these are just placeholders.

I think it is pronounced YeeHawWooHoo
