Noun

1. A punishment or reward that is considered to be what the recipient deserved.

   It may appear that they're getting ahead by cheating, but they'll get their just deserts in the end.

Usage notes

• Deserts here is the plural of desert, meaning "that which one deserves". It is rarely used with this meaning outside this phrase.
• The spelling just desserts is commonly seen but is incorrect. The misspelling is occasionally used deliberately as a play on words.
