The word "zenith" derives from an inaccurate reading of the Arabic expression سمت الرأس (samt ar-ra's) proposed by ancient Persian astronomers, meaning "direction of the head" or "path above the head", by Medieval Latin scribes in the Middle Ages (during the 14th century), possibly through Old Spanish. It was reduced to 'samt' ("direction") and miswritten as 'senit'/'cenit', as the "m" was misread as an "ni". Through the Old French 'cenith', 'zenith' first appeared in the 17th century.
