régnerai

Régnerai is the first-person singular future simple form of the French verb régner, meaning to reign or to rule. It denotes a future action or state in which the subject will hold sovereign power over a realm or domain.

Etymology and form: Régner comes from Old French regner, ultimately from Latin regnare, from regnum “kingdom” or rex “king.” The form régnerai preserves the infinitive endings with the standard future simple endings for -er verbs.

Conjugation and usage: je régnerai, tu régneras, il régnera, nous régnerons, vous régnerez, ils régneront. Régner is a regular -er verb for the future; in passé composé it takes the auxiliary avoir: j'ai régné.

Usage: The form is common in historical or literary contexts and in expressive or prophetic statements. It can convey ambition, destiny or power, for example: Je régnerai sur ces terres... or, more figuratively, régner sur un domaine professionnel. While rare in everyday speech, it appears in narratives, poetry and rhetoric to project sovereignty or mastery.
