The Hebrew Language Origins of English
English Word from Hebrew. IS from "as."
We have the Hebrew word "AS" from the word root "A-S-H" or "E-S-H." This gives us "aseh" meaning "do, make." In verbal form it can become "ya-as" or simply "as".
In Hebrew verbal sounds are quite fluid so that "as" could easily have been rendered as "as" or as "es", or as "is."
This is also the root of the name "Esau" connoting "done," or "already made".
Esau gave us the Celtic god "Esus." According to Jacques Martin, 1727, the Greek deity "Zeus" is identical to the Celtic Esus.
