What is "devinalh"

The devinalh (, roughly meaning "guesswork"), was a genre of Old Occitan lyric poetry practiced by some troubadours. It takes the form of a riddle, or series of riddles or cryptograms and is, if read literally, mostly nonsensical. Known practitioners include Guilhen de Peiteu, Raimbaut of Orange, Giraut de Bornelh, Guilhem Ademar, Guilhem de Berguedan and Raimbaut de Vaqueiras.

The term was created by modern scholars of Old Occitan and was never used by the troubadours themselves to refer to a specific type of poem.
