Adonai

Adonai is a Hebrew title used when addressing or referring to God, commonly translated my Lord. Its grammatical form is plural, but in Jewish prayer its divine use is singular. It is especially familiar as the spoken substitution for the sacred four-letter divine name in readings and worship.

Because of that religious role, Adonai has a different cultural position from ordinary biblical personal names such as Daniel or Samuel. Some Jewish communities reserve its pronunciation for prayer and use other expressions in everyday speech. It does appear as a modern registered given name outside that traditional practice. Parents considering it should understand that its main history is as a sacred title, rather than as the name of a human biblical figure.
