crusader

Etymology

It is formed from English crusade + -er.^[2][3][4] The OED compares French croisadeur, recorded by Cotgrave in 1611,^[2] and Etymonline gives an earlier English form croisader, from the French word.^[4] The noun it is formed on, recorded from 1706, replaced croisade (1570s), from Middle French croisade and Spanish cruzada, both from Medieval Latin cruciāta, the past participle of cruciō (“to mark with a cross”), from Latin crux (“cross”).^[4] The OED adds that the French noun was an alteration of earlier croisee with the suffix -ade, partly after Old Occitan crozada and the Spanish word.^[2]

Earliest recorded meaning

A person who takes part in a crusade, especially one of the medieval crusades to the Holy Land: before 1701, in Henry Maundrell's Journey from Aleppo to Jerusalem.^[2] Etymonline dates the word to 1743.^[4] The OED notes an isolated earlier form, croseidiers, in a translation of 1547.^[2]

Semantic evolution

In Middle English a crusader might simply be called a pilgrim, and to go on crusade was to take the cross.^[4] The figurative sense, a person who campaigns passionately for a cause, especially for moral or social reform, is recorded from 1785, in the parliamentary register of Ireland.^[2] American campus slang of the 1990s used crusader for an evangelical Christian who tries to convert others.^[5]
