The quality of being without fear; courage and bravery in the face of danger or difficulty.
From 'fearless' (fear + -less, meaning 'without') plus the noun-forming suffix '-ness.' The word entered English in the 16th century to describe the absence of fear.
Warriors and revolutionaries built their reputations on fearlessness, making it one of the most glorified human qualities in literature—yet ironically, modern psychology suggests that true fearlessness might indicate a neurological difference rather than courage.
