The Origin of Superseded vs Superceded

The confusion comes from the word’s unusual history.

The word supersede comes from the Latin word supersedere, which means to sit above, to refrain from, or to replace.

It is made up of:

Part	Meaning
Super	Above
Sedere	To sit

Over time, the word entered English as supersede.

Many people assume it should be spelled supercede because several English words ending in -cede come from the Latin root cedere (“to go” or “yield”), such as:

• precede
• recede
• concede
• intercede

However, supersede does not share that root. It comes from sedere, not cedere.

That is why the spelling remains supersede and not supercede.
