Adonai
Adonai (אֲדֹנָי, adonay). A name for God, which is translated “Lord.” Its vowels are found in the Masoretic Text with the proper name for God: יהוה (yhwh) (YHWH; also called the tetragrammaton). In Jewish tradition, when reading the Hebrew text, one substitutes “Adonai” instead of pronouncing the tetragrammaton.
