Answer: Such words are not used in everyday life because there are no Keter, Hochma, Bina, Zeir Anpin, and Malchut in our earthly nature.
The language of Kabbalah stems from the essence of objects that exist in the spiritual world.
The language that exists in the upper world doesn’t fully descend into our world because, on the one hand, there are many more spiritual objects there than their revelations in our world. On the other hand, there are more and more artificial objects in our world, which are manmade that we give names to.
The word “telephone,” for example, in Hebrew is “Sah Rahok,” (Sah, Shihan – conversation, Rahok – remote) distance speaking, which means that it is means for distance conversation, but this word has not been accepted, just like many other words, because the names of many objects come to us from the West, from the world where they appeared.
