noun / verb

reign

RAYN/reɪn/

Holding power or control over a place or situation.

The queen reigns from her coronation until a successor takes the throne.

Etymology

Latin regnum named kingship, rule, or a realm. The English word also came to name the span of time during which a particular monarch held that royal power.
