Origin of Supersede

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.

From Wiktionary
Late Middle English (Scottish) superceden to postpone, defer from Old French superceder from Latin supersedēre to sit on top of, abstain from super- super- sedēre to sit sed- in Indo-European roots
