The word, god, is traced back to Sanskrit, however the actual ource of the word, god, in Sanskrit is not known to etymologists.
The Hebrews called gods, men of great strength. This word transliterated from Hebrew would be pronounced Elohim, thus Elohim with the capital is oour Almighty. Used with a small letter it is the equivalent to what we are meaning when we say god(s).
When Moses spoke to God, he asked Him who he should say sent Him to the Hebrews. God said, tell them Yahweh has sent you. Yahweh is the noun (gerund) form of the Hebrew verb to be. Used here it is transitive or active meaning only the One Who Created all could use this title in honesty for it does not simply mean He is, but He is Self-existing. Nothing reated may say this in honesty.
Having said this, I know when people say God they mean Yahweh, but those of you who do say God do not ever fault anyone for using the name, Yahweh.
No one knows God' true name, and He has promised in Zephaniah, come the KIngdom He is going to give us one tongue (language), so that we will be able to call Him by One Name.......I believe it will be His true name, but this too is a mystery to be revealed and not torn out of His understanding by mere creatures.
So, the name He has given mankind truly is Yahweh. Do not go off on this. I love to call Him by the name I know He supplied Moses, but I also know others mean Yahweh when they say God, so do ot argue this.........it has no bearing on Salvation, though it does open our eyes to many teachings revealing many otherwise hidden understandings............
I also like the name, Yeshua, meaning, the Salvation of Yah(weh). I know Jesus is the same name though afew steps furtherly6 transliterated.........Jesus christ is God. Yeshua Mashiach is Elohanu..........
