Angry words as aid returned by large family? (8)
I believe the answer is:
diatribe
'angry words' is the definition.
(a diatribe is an angry speech)
'aid returned by large family?' is the wordplay.
'returned' is a reversal indicator.
'by' means one lot of letters go next to another.
'large family?' becomes 'tribe' (tribe can humorously mean a large family).
'aid' back-to-front is 'dia'.
'dia'+'tribe'='DIATRIBE'
'as' acts as a link.
(Other definitions for diatribe that I've seen before include "I debar it, being a violent attack in words" , "Loud verbal attack" , "Vitriolic speech" , "stream of abuse" , "Hostile rant" .)
