proeza

prowess (bravery or courage, especially in battle); feat (heroic or extraordinary deed)

Inherited from Old Spanish proeza. Coromines and Pascual suspect that because Old Spanish pro was not an adjective (meaning 'brave', cf. Old French preu), the Old Spanish term was probably borrowed from Old French proece (> modern French prouesse), or alternatively from Old Occitan proeza or an Old Catalan proeza. Ultimately derived from Late Latin prōde + Latin -itia.
