noun, feminine/kʁwa.zad/plural: croisades
crusade
Inherited from Middle French croisade (15th century), as it were crois + the suffix -ade. The change in suffix from Old French croisement, croiserie, croisée, is influenced by Old Occitan crozada (13th century) and Old Spanish cruzada (14th century), both reflecting Latin cruciāta.
