"Jehovah" is the name of God. No one invented him.
Jehovah God
The modern day history of Jehovah's Witnesses started with Charles Taze Russell.
The word JEHOVAH is a modern hybrid made by inserting the vowels of the word adonai into the tetragrammaton JHVH.
The Hebrew Tetragrammaton (4 letter word) YHWH is translated to JHVH or Jehovah in English
Simple answer; JW is the abbreviation for "Jehovah's Witnesses"
I can find no reference to the name Jehovah in the word aslan. The word aslan is a Turkish word meaning lion.
The word "Jehovah" is the German translation of the Hebrew word "YHWH/Yahweh". "Jehovah" entered the English language in the nineteenth century, when German scholars were at the forfront of biblical research. The modern Catholic bible would probably not have Jehovah but either the actual "YHWH" or "Lord".
The Tagalog word for "Jehovah" is "Jehova." It is used to refer to God in the Christian context, particularly by members of the Jehovah's Witnesses denomination.
The abbreviation for Jehovah would be YHWH, like in the original scriptures. ==Another possibilty== The name Jehovah can be abreviated "Jah." The word Halelujah uses this abreviation, because it actually means "praise Jah."
The likely word is the possessive plural noun Jehovah's (e.g. the Christian sect Jehovah's Witnesses).
The name Jehovah is not used in the English Standard Version of the Bible.
