How do you pronounce the Egyptian gods name Seth?

Answer 1

You can pronounce them any way you like and you will be wrong every time, because we do not accurately know how anyancient Egyptian words were pronounced.

Hieroglyphs only record consonants, not vowels (exactly as in ancient Arabic, Phoenician and Hebrew) - the people at the time knew which vowels to include, but that knowledge is lost today.

Many people pretend to know how to say the names of gods and goddesses (for example pronouncing Seth as Set) but they are fantasising and misleading others. The name of that particular god is written in hieroglyphs as stx (s+t+kh) and it was definitely not pronounced as either Seth or Set.

Isis and Osiris are both later Greek forms of the real Egyptian names, which are written Ast and wsir in hieroglyphs, where the A and i represent consonant sounds not present in English.

Bes, Geb, Anubis, Taweret, Horus, Bastet, Neith, Thoth, Hathor, Amun, Tefnut and Mut (and the names of hundreds more) are all very modern guesses at how the names might have been said - and all are incorrect. Those names are written in hieroglyphs as bs, gb, inpw, twrt, Hr, bAstt, nt, DHwty, Hwt Hr, imn, tfnt, mwt.

Scholars need to be able to write and talk about these deities so having more pronounceable names like Thoth (as opposed to DHwty) is convenient and widely accepted, but always entirely inaccurate.

Answer 2

It is pronounced like Set. The h is silent.
