An archaic term for a crusader, someone who participated in a crusade.
From Old French 'croisard' (crusader), formed from 'crois' (cross) + suffix '-ard.' The '-ard' suffix in French often implies someone who does something excessively or is characterized by something.
The '-ard' suffix in 'croisard' is the same one that gave us words like 'drunkard' and 'coward'—so a 'croisard' was literally someone marked by the cross, carrying that identity as their defining characteristic.
