Kind of shade worn by bishop, possibly (6)
I believe the answer is:
humane
'kind' is the definition.
(similar in meaning)
'shade worn by bishop possibly' is the wordplay.
'shade' becomes 'hue' (both can mean a colour).
'worn by' indicates putting letters inside (outside letters are worn by those on the inside).
'bishop possibly' becomes 'man' (bishop is a kind of man).
'hue' placed around 'man' is 'HUMANE'.
'of' acts as a link.
(Other definitions for humane that I've seen before include "Benign - kind" , "Showing compassion for animals" , "Compassionate, benevolent" , "Kindly and compassionate" , "Compassionate, merciful" .)
