Present banking pass for bank (8)
I believe the answer is:
gradient
'bank' is the definition.
(I've seen this before)
'present banking pass' is the wordplay.
'present' becomes 'grant' (granting is a kind of presenting).
'banking' indicates putting letters inside.
'pass' becomes 'die' (as in passing away).
'grant' going around 'die' is 'GRADIENT'.
'for' acts as a link.
(Other definitions for gradient that I've seen before include "Angle of slope" , "Degree of slope in a road" , "Third OT book" , "Level of steepness" , "Measure of slope" .)
