The word 'syntactical' is built upon the Greek roots for "together" and "arrangement." Its core ancestor is the Greek word syntaktikos, meaning "pertaining to arranging together," which itself derives from syn (together) and tassein (to arrange). This concept of orderly arrangement was adopted into Latin as syntacticus and entered English via Late Latin. The modern term retains this foundational logic, specifically applying the idea of systematic arrangement to the ordering of words and phrases to form grammatically correct sentences.
