ardor

Ardor is a noun that denotes intense enthusiasm, passion, or burning zeal. It can refer to strong emotional energy in romantic, intellectual, artistic, or activist contexts, and it is often used to describe a determined, wholehearted pursuit of a goal. While generally positive, ardor can be interpreted as excessive or impulsive when it overrides judgment or leads to fanaticism.

Etymology: from Latin ardor meaning “glow, heat,” from ardere “to burn.” The spelling ardour is used in British English. The adjective ardent and the adverb ardently derive from the same root.

Usage notes: In formal or literary language, ardor invites a sense of sincerity and commitment. Common collocations include “ardor for knowledge” or “ardor for art.” Its tone can vary with context, from inspirational to intense. The term is typically not used for mundane enthusiasm; it emphasizes a strong, enduring energy that drives action or belief.

In culture and rhetoric: Ardor is often invoked to characterize characters or speakers who pursue ideals with unwavering energy. It can function as a positive motivator or, when uncontrolled, as a source of conflict or recklessness. The concept is closely related to fervor, zeal, and enthusiasm, though ardor traditionally carries a more personal, heart-felt charge.
