The word 'strategy' originates from the Greek stratēgia, meaning "the office or command of a general." This was formed from stratēgos, "a general," which itself is a compound of stratós (army) and agein (to lead). The literal sense is thus "the leading of an army." The core concept of stratós evolved from the idea of something "spread out" (from the PIE root stere- "to spread") to specifically denote a military encampment or army. Over time, the term broadened from purely military command to encompass the art of high-level planning and management in any complex field, reflecting the abstract application of a general's skills to competitive non-military endeavors.

Structure: strat (army, spread) + egy (act of leading, noun suffix) - strat: From Greek stratós meaning "army, multitude, that which is spread out." In this word, it functions as the core root conveying the concept of a large, organized body. - egy: A suffix derived from Greek -agein (to lead), via -agōgia and Latin -egia, forming nouns meaning "the act or art of leading." It indicates a field of practice or a system of management.
