This adjective describes something endless or unlimited, whether in space, time, or number. Classical Greek applied it to boundless plains, endless time, countless multitudes, or unlimited punishments. Paul uses it in 1 Timothy 1:4 to warn against 'myths and endless genealogies.' These genealogies—perhaps speculative Jewish genealogical systems or Gnostic emanation chains—were 'aperantos,' leading nowhere productive. The term emphasizes futility through boundlessness: discussions that never reach conclusion because they never exhaust their self-generating complexity.
