[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; see sed- in Indo-European roots.]

Usage Note: Supersede is commonly spelled supercede, probably by influence of words like accede and intercede. The spelling with a c has been in existence for 300 years and has traditionally been considered an error, but it appears so widely in books and other edited publications that this spelling must be considered standard.
