Give the original language from which this term was derived. chivalry Dutch Greek Hebrew Latin Old French

Answer 1

The origins of the word "chivalry" can be traced from Middle Latin in which the word was "caballerius", then in the Late Latin the word changed to "caballarius". From both Middle and Late Latin derived the old French word "cavalerie", which was "chivalry" in Middle English,  and it is "chevalier" in Modern English meaning the name given to old and young pretenders.

Answer 2

The original language from which chivalry was derived is Medieval Latin. 
In that language, the word caballus (horse) serves as the original word for today's chivalry.
