An Etymological Dictionary of the German Language/Abenteuer

by Friedrich Kluge

Abenteuer, n., ‘adventure,’ from MidHG. âventiure, f., ‘occurrence, a marvellous, fortunate event, a poem on such a theme, sources of the court poets’; the latter is derived from Fr. aventure (MidLat. adventura, allied to MidLat. and Rom. advenire, ‘to happen’).
