From Middle French superseder (“postpone, defer”), from Latin supersedere, from super (“over”) + sedere (“to sit”). The meaning “to replace” is from 1642, probably by association with unrelated precede – note that ‘c’ instead of ‘s’ (from cedere (“to go”), not sedere (“to sit”)). As a result, supercede is a common misspelling – see therein for further discussion.

Supersede is the only English word ending in sede. Similar words include four ending in ceed, and several ending in cede (apart from seed). Because of this, supercede is a common misspelling of this word.
