The word "tactics" originates from the Greek taktikē (tekhnē), meaning "the art of arrangement," specifically the arrangement of military forces. This Greek term is derived from tassein, a verb meaning "to arrange, to put in order." The core concept passed into Latin as tactica and entered English in the 17th century, retaining its primary military sense. Over time, the meaning broadened from the literal arrangement of troops on a battlefield to signify any systematic method or skillful plan employed to achieve an objective in various competitive or strategic contexts.
