Adonai

Judaism has different names given to God, which are considered sacred: יהוה, אֲדֹנָי, אֵל, אֱלֹהִים, שַׁדַּי, and צְבָאוֹת ; some also include I Am that I Am. 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. 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 Hebrew number sixteen.
