Root Breakdown
Root-derivedsuper- (above, over) + sede (sit) = 'to sit above' — to set yourself over something and so take its place. Note the rare spelling: supersede ends in -sede (from sedēre), NOT -cede. It is the only common English word that does this.

Spelling trap: it is -sede, not -cede or -ceed. Supersede is the ONLY English word ending in -sede (compare precede, recede, proceed). Because it comes from sedēre 'to sit,' not cedere 'to go.' Register is formal — used of rules, editions, technologies, not casual replacement.
