Lese is a Central Sudanic language of northeastern Congo-Kinshasa, as well as a name for the people who speak this language. The Lese people, who live in association with the Efé Pygmies, share their language, which is also occasionally known as Lissi or Efe.Although Efe is given a separate ISO code, Bahuchet (2006) notes that it is not even a distinct dialect, though there is dialectical variation in the language of the Lese (Dese, Karo).
