Violent quarrel between family members and household servant (8)
I believe the answer is:
domestic
This clue is a double definition.
'violent quarrel between family members' is the first definition.
'household servant' is the second definition.
(I've seen this before)
'and' is the link.
(Other definitions for domestic that I've seen before include "Family quarrel" , "Internal; servant" , "Tame - row - maid" , "Servant - not foreign" , "Concerning internal affairs" .)
