recur

Etymology

This is a learned borrowing from Latin recurrō ("to hurry or run back; to return, revert"), itself made up of re- (a prefix meaning 'back, backwards') and currō ("to hasten, hurry; to move, travel; to run"), which ultimately goes back to the Proto-Indo-European root *ḱers- ("to run"). Related forms appear in other languages too: Anglo-Norman recurre, recorre ("to have recourse to"), Catalan recórrer, Italian ricorrer, Old French recourir (Middle French recourir; modern French recourir, meaning "to have recourse to; to run again; to run back"), Old Occitan recorre, Portuguese recorrer and Spanish recorrer.
