Elaborating on what the colleagues say I do not know if I will contribute something new but I like the word. The four-letter word whose etymology furoya speaks to us and which we transcribe as Yahweh or Yahweh, lengthening the first vowel, by the Hebrew letters written backwards in that language, the yod (our i or y), the he (our a, e), the waw (our v, f, w, u) and again the he. The Greek texts translated it as kyrios and the Latins as dominus, lord or lord and others with less reverence, master, master, chief.
Par excellence, the name of God (for the consonants YHWH), "4 letters". It comes from the Greek 964; 949; 964; 961; 945; (tetra, "four") and 947; 961; 945; 956; 956; 945; 964; 949; 953; 959; 957; (grammateion, "writing"); even if you don't have a reference in the Greek manuscripts of the Judeo-Christian holy books.
