Cunning schemes Friar Tuck conceals (3)
I believe the answer is:
art
'cunning' is the definition.
(I've seen this before)
'schemes friar tuck conceals' is the wordplay.
'conceals' indicates a hidden word.
'ART' is hidden in the letters of 'schemes friar tuck'.
(Other definitions for art that I've seen before include "The works of Alma-Tadema" , "Works of beauty created by humans" , "Creative works; skill" , "Beautiful or significant products of human creativity" , "Trickery" .)
