What does Mordechai mean?

The name Mordechai is a Hebrew name derived from the Biblical figure Mordechai, who appears in the Book of Esther.

In the Book of Esther, Mordechai is depicted as the cousin and guardian of Queen Esther, who played a pivotal role in saving the Jewish people from genocide at the hands of the Persian king's advisor, Haman.
