Etymology
the word 'prowess' entered english in the 13th century from the old french 'proesce' or 'prouesce', meaning 'bravery, valour, excellence'. this old french term derived from the adjective 'prou' or 'proz', signifying 'valiant, brave'. the ultimate origin is the vulgar latin 'prodis', a form related to the classical latin 'prodesse', meaning 'to be of use or value', itself a compound of 'pro-' (for, forward) and 'esse' (to be). the semantic journey thus moved from the fundamental idea of 'being of value' to the specific, chivalric qualities of 'valour' and 'martial skill', which were highly prized in medieval society, before broadening again in modern english to denote outstanding skill or ability in any field.
