Etymology

Derived from the Greek word "logikē," which is the feminine form of "logikos," meaning pertaining to reason. This stems from "logos," a multifaceted term meaning word, reason, or discourse. It entered English via Old French and Latin, evolving from a philosophical study of the laws of thought into a general term for systematic reasoning.
