Linguistic Origin & Historical Etymology

Derived from Middle English ardour, borrowed through Anglo-Norman and Old French from the Latin ardor ('heat, fire, passion'). The underlying root is the Latin verb ardēre, meaning 'to burn'. Over the centuries, its literal sense of intense physical heat expanded metaphorically to denote burning emotion, zeal, and devotion.
