In ancient Greek, describing someone or something that is unarmored or without defensive protection.
From Greek 'a-' (without) and 'kepira' (armor). This adjective was used in classical literature to describe both warriors and abstract concepts lacking protection or defense.
Greek philosophers loved using military metaphors—they'd describe an argument or person as 'akepiros' (unarmored) when vulnerable, showing how ancient people thought about abstract ideas through physical combat.
