Middle English superceden, to postpone, from Old French superceder, from Latin supersedēre, to refrain from : super-, super- + sedēre, to sit; see sed- in Indo-European roots.(American Heritage® Dictionary of the English Language, Fourth Edition)
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. (Wiktionary)
