Did You Know?
The origin of regnant is straightforward: it comes from the Latin verb regnare, meaning "to reign."
Regnare, in turn, traces back to the noun regnum, meaning "reign."
(Regnum was bestowed with the meaning "kingdom" in English.)
These words ultimately descend from rex, the Latin for "king" and a word familiar to those who have read or seen the Greek tragedy Oedipus Rex.
