A little background on the word - you know that it comes from the verb hawah, meaning to become or exists. In Hebrew thought, that which exists has breath, and the breath was the character of someone. Hawah comes from the primary root, hah, or heh [HH] – which if you open your mouth wide and blow the air from your lungs, you will have pronounced this ancient root word. There are many derivatives which come from HH – hawah [to become or exist]; hayah [to breath, was, come to pass]; chayah [live, life, exist]; neshamah [to blow, or wind from the lungs]; yihyeh [he exists] and so on. HH in the paleo is made up of two “hey”, and the pictograph letter for hey, was the little man, standing with his arms raised out, which singularly, means to “behold” as when looking at a great sight [one might throw their arms up or out in amazement or wonderment], and when beholding a great sight, one often takes in a deep breath, or even “sigh”, with the extended meaning then of “reveal” as well – with the two hey, you have both – a great sight or wonderment itself being the very revealing of life’s breath.
The Waw was the picture of the tent peg, meaning just that, a peg or hook, used to secure something, fixed it in place, even “add” – as the waw is often used and a prefix to words to mean “and” in the sense of adding things together, or bringing together.
The Yad was the side-view of the arm and hand meaning to work, make, throw – all the functions of the hand and arm working together. The Modern Hebrew name “yud” is a derivative of the two letter word “yad” meaning "hand", the original name for the letter. or secure.
The word, yhwh, from a literal academic perspective means “he exists” or as in Genesis 15:6, “b’yhwh“ meaning the “fully existent one”
Yhwh is derived from the root Hh [see above] by placing the Yad in the beginning, or in front of the Hh, and is completed by inserting the waw between the Hh.
By his very own action, his own hand’s work [yad], he is the one to which all life’s breath, wonderment, and revelation [hey hey] are secured and brought together [waw]. He is the very cause and securing factor, of all that exists – that which we call the wonderment or revelation of life through every breath we take.
