The English word "grammar" traces its etymological lineage back to ancient Greek through Latin and Old French. It originates from the Greek term "grammatikē technē", which translates literally to "art of letters", derived from "gramma", meaning a letter of the alphabet or a written mark. In antiquity, this encompassed the comprehensive study of literature, reading, and writing. The term passed into Latin as "grammatica" and later entered Middle French and Middle English as "grammaire" or "gramere". During the medieval period, the word specifically denoted the study of Latin, which was the universal language of scholarship, science, and the Church across Europe. Over subsequent centuries, the definition broadened to describe the structural rules, syntax, morphology, and phonology governing any spoken or written human language.
