Craft gin trade to show rise (8)
I believe the answer is:
gradient
'rise' is the definition.
(I've seen this before)
'craft gin trade' is the wordplay.
'craft' indicates anagramming the letters (letters must be crafted into a new form).
'gin'+'trade'='gintrade'
'gintrade' with letters rearranged gives 'GRADIENT'.
'to show' acts as a link.
(Other definitions for gradient that I've seen before include "Inclination" , "Treading (anag) - slope" , "Measure of slope" , "Angle of slope" , "Slope or incline" .)
