Acting without following rules or laws; wild and uncontrolled.
From 'law' (Old English: lagu, from Old Norse) plus the suffix '-less' (meaning 'without'). The combination literally means 'without law.'
Societies throughout history go through 'lawless' periods called 'anomie' by sociologists—and these periods actually peak right after laws change suddenly, because people haven't adjusted their behavior patterns yet to the new rules.
