disobedience (n.)

"neglect or refusal to obey," c. 1400, from Old French desobedience, from Vulgar Latin *disobedientia (replacing Latin inobedientia) from Latin dis- (see dis-) + oboedientia "obedience," abstract noun from oboedientem (nominative oboediens), present participle of oboedire "to obey" (see obey). The English word replaced earlier desobeissance in this sense, and inobedience (c. 1200).
