For poet, at no time stopping chorus of contempt (8)
I believe the answer is:
sneering
'contempt' is the definition.
(sneering can mean contempt or disrespect)
'for poet at no time stopping chorus' is the wordplay.
'for poet at no time' becomes 'neer' ('ne'er' is a poetic variant of 'never').
'stopping' is an insertion indicator (stopping can mean blocking a gap).
'chorus' becomes 'sing' (I've seen this before).
'neer' placed inside 'sing' is 'SNEERING'.
'of' acts as a link.
(Other definitions for sneering that I've seen before include "Showing scorn or contempt" , "Smiling contemptuously" .)
