charioteer

the word 'charioteer' is a relatively modern english formation, combining the noun 'chariot' with the agent suffix '-eer'. 'chariot' itself has a long history, entering english from old french 'chariot', a diminutive of 'char' (car), which traces back to the latin 'carrus', a wheeled vehicle. the suffix '-eer', borrowed from french, ultimately derives from latin '-arius', commonly used to denote a person associated with a specific thing or activity. therefore, the literal construction is "one who is engaged with a chariot," a perfectly transparent description for the driver of a horse-drawn racing or war vehicle used in ancient times.

Structure: chariot + eer chariot (from old french, ultimately latin 'carrus', meaning a wheeled vehicle) + eer (from french '-ier', latin '-arius', a suffix forming agent nouns meaning 'one who is concerned with or engaged in').
