Zenith is the highest point that something reaches, either in the sky or in success or power. In astronomy, it is the point directly above your head.
“Zenith” comes from medieval Latin “cenit,” a mistaken copying of Arabic “samt (ar-ra’s),” meaning “direction (of the head).” Through copying errors and translations, the word changed shape and entered European languages.
Zenith is a word born from a chain of mis-hearings and mis-writings across languages—an error that became official. It shows how even mistakes can rise to the ‘highest point’ in dictionaries.
