Complained a good bit, with foolish pride (6)
I believe the answer is:
griped
'complained' is the definition.
(griping is a kind of complaining)
'a good bit with foolish pride' is the wordplay.
'a good' becomes 'g' (abbreviation).
'bit with foolish pride' becomes 'riped' (I am not sure about this - if you are sure you should believe this answer much more).
'g'+'riped'='GRIPED'
Can you help me to learn more?
(Other definitions for griped that I've seen before include "Complained persistently" , "Moaned constantly" .)
