The word 'undaunted' is built upon the core verb 'daunt,' which traces its lineage to the Latin domāre, "to tame or subdue," a concept rooted in the Proto-Indo-European base dem(h₂)-, "to constrain, force." The prefix 'un-', a common Germanic negation, was attached to the past participle 'daunted' to create an adjective. Thus, the literal construction "not tamed or subdued" evolved into the modern abstract sense of remaining resolutely courageous and undiscouraged in the face of challenges, preserving the metaphorical link between overcoming a threat and maintaining one's spirit.
