Disputes in banks (4)
I believe the answer is:
rows
I believe this is a double definition.
'disputes' is the first definition.
(row is a kind of dispute)
'banks' is the second definition.
(I've seen this before)
'in' is the link.
(Other definitions for rows that I've seen before include "Angry disputes" , "Scraps" , "Banks" , "Tiers" , "Arrangements side by side in lines" .)
