name chosen by a reigning monarch, different from their original secular name
- Example: Edward VII of the United Kingdom, born Albert Edward of Saxe-Coburg and Gotha
A pope chooses a regnal name when he is elected. It becomes his new personal name.
- Example: Pope John Paul II, born Karol Józef Wojtyła,
The new name -- or sometimes the old one -- is followed by an ordinal number to create a unique name for the period in which the monarch is on the throne.
- Example: Elizabeth II was queen of the United Kingdom and many other Commonwealth Realms until her death in 2022
