Companionship displayed by river, on a road, around a lake (11)
I believe the answer is:
camaraderie
'companionship' is the definition.
(thesaurus)
'river on a road around a lake' is the wordplay.
'river' becomes 'cam' (river in Cambridge, England).
'on' means one lot of letters go next to another.
'a road around' becomes 'arad' (I can't justify this - if you can you should give a lot more credence to this answer).
'a lake' becomes 'erie' (Lake Erie is one of the Canadian/US 'Great Lakes').
'cam'+'arad'+'erie'='CAMARADERIE'
'displayed by' is the link.
Can you help me to learn more?
(Other definitions for camaraderie that I've seen before include "Main theme of Friends" , "all that backslapping?" , "Spirit of friendliness and trust" , "Friendly feeling" , "Fellowship" .)
