Complaint from a bishop during awkward chat (7)
I believe the answer is:
catarrh
'complaint' is the definition.
(medical complaint)
'a bishop during awkward chat' is the wordplay.
'bishop' becomes 'rr' (abbreviation for Right Reverend).
'during' is an insertion indicator.
'awkward' indicates anagramming the letters.
'a'+'rr'='arr'
'chat' is an anagram of 'cath'.
'arr' placed into 'cath' is 'CATARRH'.
'from' is the link.
(Other definitions for catarrh that I've seen before include "Arch rat with inflamed mucous membrane" , "Nasal build-up" , "Nasal inflammation" , "cold symptom" , "Nasal congestion" .)
