Little woman breaks up row begun by a neighbour (6)
I believe the answer is:
adjoin
'neighbour' is the definition.
(both can mean to be located next to)
'little woman breaks up row begun by a' is the wordplay.
I cannot quite see how this works, but
'woman' could be 'jo' and 'jo' is present in the answer.
'row' could be 'din' (both can mean a loud disturbance) and 'din' is present in the remaining letters.
'a' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for adjoin that I've seen before include "Be nineteen [NEXT]" , "Abut, border" , "Neighbour" , "Be next or nearest to" , "Lie adjacent to another" .)
