Nasty remarks in lodgings (4)
I believe the answer is:
digs
I believe this clue is a double definition.
'nasty remarks' is the first definition.
(I've seen this in another clue)
'lodgings' is the second definition.
(synonyms)
'in' is the link.
(Other definitions for digs that I've seen before include "Lodgings - snide remarks" , "Temporary lodgings" , "(Temporary) living quarters" , "Lodgings, informally" , "Archaeological excavations" .)
