Admit accepting end for bank (8)
I believe the answer is:
gradient
'bank' is the definition.
(thesaurus)
'admit accepting end' is the wordplay.
'admit' becomes 'grant'.
'accepting' is an insertion indicator.
'end' becomes 'die'.
'grant' going around 'die' is 'GRADIENT'.
'for' is the link.
(Other definitions for gradient that I've seen before include "Measure of slope" , "Level of steepness" , "Bank" , "Inclination" , "Degree of slope in a road" .)
