Credit for one's achievements.

Usage notes

• The noun kudos was originally a mass noun, but in American English is now sometimes treated as a plural noun, either as a plurale tantum, or as the plural of a new noun kudo, contrary to the original Greek κῦδος, which is a singular noun. The American pronunciation implies this plural usage, which many authorities nevertheless consider erroneous.

Etymology 2

Noun

kudos

plural of kudo Note that 'kudo' is itself a backformation from kudos under the (mistaken) idea that kudos, because it ends in the letter 's', is a plural.
