στρατός

Etymology: From Ancient Greek στρατός (stratos), meaning 'army' or 'encamped army'. The word has Indo-European roots related to 'spreading out' or 'extending', reflecting how armies would spread across a field. English military terms like 'strategy' and 'strategic' derive from the related Greek word στρατηγία (strategia), which literally meant 'generalship' or 'the art of the general (στρατηγός/strategos)'.
