Price fruit higher than flower (6)
I believe the answer is:
figure
'price' is the definition.
(thesaurus)
'fruit higher than flower' is the wordplay.
'fruit' becomes 'fig' (fig is a kind of fruit).
'higher than' is a charade indicator (letters next to each other) (some letters go above others).
'flower' becomes 'ure' (river in Yorkshire).
'fig'+'ure'='FIGURE'
(Other definitions for figure that I've seen before include "Shape; amount of money" , "Reckon" , "Shape; number" , "Person's bodily shape" , "Build" .)
