Bishop working with one in residence shows friendliness (8)
I believe the answer is:
bonhomie
'friendliness' is the definition.
(I know that bonhomie is a type of friendliness)
'bishop working with one in residence' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'working' becomes 'on' (on can mean working or activated).
'with one' becomes 'i' (Roman numeral. I am not sure about the 'with' bit.).
'in' means one lot of letters goes inside another.
'residence' becomes 'home' (home is a kind of residence).
'i' put within 'home' is 'homie'.
'b'+'on'+'homie'='BONHOMIE'
'shows' is the link.
Can you help me to learn more?
(Other definitions for bonhomie that I've seen before include "Genial manner from hobo in me" , "good humour" , "Good-natured friendliness" , "Warmth" , "convivial feeling" .)
