Lack of correspondence or disagreement between things; failure to match or agree with each other.
From dis- (prefix meaning 'not' or 'lack of') + correspondence + -ency (a noun-forming suffix). The word means the opposite of correspondence or agreement.
This is an incredibly formal and archaic word—scholars today would just say 'disagreement' or 'mismatch,' but in historical texts you'll find it describing philosophical and scientific disputes!
