Adonai in the context of Chumra (Judaism)

Judaism has different names given to God, which are considered sacred: יהוה (YHWH), אֲדֹנָי (Adonai transl. my Lord[s]), אֵל (El transl. God), אֱלֹהִים (Elohim transl. Gods/Godhead), שַׁדַּי (Shaddai transl. Almighty), and צְבָאוֹת (Tzevaot transl. [Lord of] Hosts); 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 (טו, lit. '9-6') instead of Yōd-Hē (יה, '10-5', but also 'Jah') for the number fifteen or Ṭēt-Zayin (טז, '9-7') instead of Yōd-Vav (יו, '10-6') for the Hebrew number sixteen.

Jehovah (/dʒɪˈhoʊvə/) is a Latinization of the Hebrew יְהֹוָה‎ Yəhōwā, one vocalization of the Tetragrammaton יהוה‎ (YHWH), the proper name of the God of Israel in the Hebrew Bible / Old Testament. The Tetragrammaton is considered one of the seven names of God in Judaism and a form of God's name in Christianity.

The consensus among scholars is that the historical vocalization of the Tetragrammaton at the time of the redaction of the Torah (6th century BCE) is most likely Yahweh. The historical vocalization was lost because in Second Temple Judaism, during the 3rd to 2nd centuries BCE, the pronunciation of the Tetragrammaton came to be avoided, being substituted with Adonai ('my Lord'). The Hebrew vowel points of Adonai were added to the Tetragrammaton by the Masoretes, and the resulting form was transliterated around the 12th century CE as Yehowah. The derived form Iehovah first appeared in the 16th century. The form Jehovah began to printed following a 17th-century development leading J to become a separate letter for printing the consonantal I.
