Benevolent chap in shade (6)
I believe the answer is:
humane
'benevolent' is the definition.
(I've seen this before)
'chap in shade' is the wordplay.
'chap' becomes 'man' (chap can mean a man).
'in' indicates putting letters inside.
'shade' becomes 'hue' (both can mean a colour).
'man' going into 'hue' is 'HUMANE'.
(Other definitions for humane that I've seen before include "Kindly or merciful" , "Compassionate, benevolent" , "Kind - compassionate" , "Kind and sympathetic" , "Showing compassion for animals" .)
