The etymology of "regnant" is fairly straightforward: English speakers borrowed the word sometime around 1600 from Latin. "Regnant" is derived from the Latin verb "regnare," meaning "to reign." "Regnare," in turn, traces back to the noun "regnum," meaning "reign," which derives from "rex," the Latin word for "king." Other descendants of "regnum" include "interregnum" ("a period between two successive reigns or regimes"), "regnal" ("of or relating to a king or his reign"), and even "reign" itself.
