(medieval history): Crusade
Formed as a hybrid of Middle French croisade and Spanish cruzada, both from the word for cross; possibly corresponding to a Medieval Latin cruciāta, cruxiata, nominative feminine singular of cruciātus originally "tormented; crucified" but from the 12th century also "marked with a cross" and in the sense "a crusade" from the second half of the 13th century. Recorded in English since the 1570s.
