Camaraderie -- working day finishes with it (10)
I believe the answer is:
friendship
'camaraderie' is the definition.
(I've seen this in another clue)
'working day finishes with it' is the wordplay.
'working day' becomes 'fri' (abbreviation for Friday. I am not sure about the 'working' bit.).
'finishes' becomes 'ends' ('end' can be a synonym of 'finish').
'with it' becomes 'hip' (both can mean cool or fashionable).
'fri'+'ends'+'hip'='FRIENDSHIP'
Can you help me to learn more?
(Other definitions for friendship that I've seen before include "Amity" , "camaraderie" , "Relation between mates" .)
