Kudos

To this great man, kudos are due. That sentence wouldn't raise many eyebrows, but kudos is not the plural of kudo. There's no such thing as "a kudo." Kudos is a Greek word (pronounced "KYOO-doss" or "KOO-doss") meaning "praise" or "glory," and you'd no more say "kudos are due" than you'd say "glory are due." Admittedly, kudos is due looks odd. Better to rewrite the sentence.
