Fearless and brave; showing no fear when facing something difficult or dangerous.
From 'daunt' (from Old French 'danter,' possibly related to Latin 'domitare' meaning 'to tame') plus '-less' (without). The word originally meant 'to tame' but evolved to mean 'to intimidate.'
Dauntless heroes appear everywhere in stories because humans are fascinated by people who seem immune to fear—yet neuroscientists now know that dauntless people feel fear too, but their brains process risk differently, making them better at pushing through!
