One who disclanders; a person who denies or refutes slander or defamatory statements about someone.
From dis- (reversal) + clander (archaic or dialectal variant of slander). This appears to be a back-formation or very rare term built on the pattern of other dis- words, though 'clander' itself is not a standard modern English word.
This word is so obscure that it barely exists in major dictionaries—it seems to be either an extremely archaic term or a theoretical construction that never gained real usage, a ghost word that was possible but never actually took hold in English.
