Conflict involving hospital and fellow in dock (5)
I believe the answer is:
wharf
'dock' is the definition.
('wharf' can be a synonym of 'dock')
'conflict involving hospital and fellow' is the wordplay.
'conflict' becomes 'war' (war is a kind of conflict).
'involving' indicates putting letters inside.
'hospital' becomes 'h'.
'and' says to put letters next to each other.
'fellow' becomes 'f' (abbreviation - of a society etc.).
'war' placed around 'h' is 'whar'.
'whar'+'f'='WHARF'
'in' is the link.
(Other definitions for wharf that I've seen before include "Waterfront landing stage" , "Loading quay" , "Landing stage for cargo" , "Landing area" , "Harbour platform" .)
