Adonai

Chambers's Encyclopaedia, Volume 1: A to Beaufort, p. 58

Adonai, a Hebrew name for the Supreme Being; a plural form of Adon, 'lord,' combined with the pronoun of the first person. In reading the Scriptures aloud, the Jews pronounce 'Adonai' wherever the holy name JHVH is found in the text; and the name 'Jehovah' has arisen out of the consonants of Jhvh, with the vowel points of Adonai.
