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 yield”), not sedere (“to sit”)). As a result, supercede is a common misspelling – see therein for further discussion. Doublet of surcease.
