Did you know?

Language is constantly evolving, with old spellings and meanings superseded by new ones over time. Naturally, supersede itself has its share of predecessors. Supersede ultimately comes from the Latin verb supersedēre, meaning "to sit on top of" (sedēre means "to sit"), "to be superior to," or "to refrain from," but it came to English through Scots Middle English, where it was rendered superceden and used synonymously with defer. Modern English speakers are often confused about how to spell supersede—it sometimes turns up as supercede. In fact, some of the earliest records of the word in English show it spelled with a c. Though both spellings can be etymologically justified, over time supersede won out as the "correct" version.
