What is Names of God in Judaism?

Judaism considers some names of God so holy that, once written, they should not be erased: YHWH, Adonai, El , Elohim , Shaddai , and Tzevaot Hosts"]; some also include Ehyeh. Early authorities considered other Hebrew names mere epithets or descriptions of God and wrote that they and names in other languages may be written and erased freely. However, some moderns advise special care even in these cases, and many Orthodox Jews have adopted the chumras of writing "G-d" instead of "God" in English or saying Ṭēt-Vav instead of Yōd-Hē for the number fifteen or Ṭēt-Zayin instead of Yōd-Vav for the number sixteen in Hebrew.
