The meaning of YHVH is easily shown: Havah (H1933) means 'to be', 'to make manifest', and thus implies the Creator.

Yah (H3050) is a two letter word, and there are many two letter words; where Ancient Hebrew stemmed from Hieroglyphics, not from a Semitic tri-root system.

In Psalms 89:8 it compares, who is a strong Yah (Lord) like YHVH; therefore Yah can not be a shortened version of YHVH.

Yah-Havah means the Lord of Creation, and is possibly a direct translation of Bhagavan Brahma, where Havah in Hebrew, and Brahma in Sanskrit mean the same thing, 'to be', 'to make manifest', and thus can imply the Creator in both.

Again with careful Bible word searches we can show that Eloh (H433) implies a Divine Being, Avatar, something that is physically manifest in some way. The addition of the H to a word in Ancient Hebrew, implies breathed by God (El - H410).

Abram became Abraham, and Sara became Sarah, when they were blessed with the breath of God to bare the Messiah from their seed.

Eloh (H433) pluralized is Elohim (H430), where Elohim refers to the Avatars, the Divine Beings; whereas polytheism made the Divine Council demigods, the correct description would be Archangels.
