Adonai n. Hebrew (ah-doe-NYE) Literally, “my Lord.” Another name for God, and the one used most often in prayers. Because God’s name is so sacred, it is not spoken as it is written. The Hebrew letters (yud, hay, vav, and hay) that spell the name are read only as Adonai. See also Adoshem, ha-Shem, and Tetragrammaton.
