Wikipedia explains a basis on YHWH, I will quote it here then continue after the quote.
“The Tetragrammaton (/ˌtɛtrəˈɡræmətɒn/) or Tetragram (from Greek τετραγράμματον, meaning “[consisting of] four letters”) is the four-letter Hebrew word יהוה (transliterated as YHWH), the name of the biblical God of Israel. The four letters, read from right to left, are yodh, he, waw, and he. While there is no consensus about the structure and etymology of the name, “the form Yahweh is now accepted almost universally”.“
As you can see above, in Hebrew Aramaic, Gods name is written on the Ten Commandments as
(read from right to left)
in English it is properly written and spoken as
Yodh He Waw He.
The nickname God comes from the root word Good.
