reigning

The word 'reigning' originates from the Latin verb regnare, meaning 'to rule', itself derived from rex (king) and the Proto-Indo-European root h₃rḗǵs (ruler, king). This root conveys the fundamental concept of straightening or directing, hence the authority of a king who sets things right. Entering English via Old French reignier, the verb 'reign' came to mean the exercise of sovereign power. The addition of the '-ing' suffix, an active participle marker from Old English, transforms it into an adjective describing the one currently holding that power or, by extension, the currently dominant force in any field.
