Without a helmet; lacking protective headgear or leadership and direction.
From English 'helm' (helmet or leadership) + '-less' (without). The word emerged in Middle English, initially referring to soldiers without armor, later extending metaphorically to describe leaderless situations.
A 'helmless' army could mean soldiers without protective gear, but metaphorically it describes any group without direction—this dual meaning shows how physical protection words evolved into symbols for guidance and leadership.
