kudos (n.) Look up kudos at Dictionary.com
"fame, renown," 1799, probably originally in university slang, from Greek kydos "glory, fame," especially in battle, literally "that which is heard of," from PIE root *skeue- "to pay attention, perceive" (see caveat). A singular noun in Greek, but the final -s often is mistaken as a plural suffix in English, leading to the barbarous back-formation kudo (attested by 1936).
