Not injured or harmed; safe and uninjured after a potentially dangerous situation.
Simple English prefix 'un-' (not) combined with 'hurt' from Old French 'hurter' meaning to strike or knock against. This Germanic-Romance hybrid entered English in the 13th century.
The prefix 'un-' is so productive in English that we can add it to almost any adjective (unhappy, unsafe, unclear), but 'unhurt' is interesting because we could just say 'fine' or 'okay'—yet we specifically reach for the negative form to emphasize that danger was involved but averted.
