Origin:
late 16th century (originally as croisade ): from French croisade, an alteration (influenced by Spanish cruzado ) of earlier croisée, literally ‘the state of being marked with the cross’, based on Latin crux, cruc- ‘cross’; in the 17th century the form crusado, from Spanish cruzado, was introduced. The blending of these two forms led to the current spelling, first recorded in the early 18th century.
