Approval, liking (6)
I believe the answer is:
favour
This clue is a double definition.
'approval' is the first definition.
(I know that favour is a type of approval)
'liking' is the second definition.
(I know that favour is a type of approval)
(Other definitions for favour that I've seen before include "back" , "Oblige or resemble" , "Prefer one over the other" , "An act of kindness or of preferance" , "Grace and - denotes housing granted by queen" .)
