Accommodation producing hurtful remarks (4)
I believe the answer is:
digs
This clue could be a double definition.
'accommodation' is the first definition.
(student accommodation)
'hurtful remarks' is the second definition.
'digs' can be an answer for 'remarks' (dig is a kind of remark). I'm not sure about the 'hurtful' bit.
'producing' acts as a link.
Can you help me to learn more?
(Other definitions for digs that I've seen before include "Delves" , "Appreciates - accommodation" , "Nasty cracks" , "Understands or approves (1950s slang)" , "flat, say" .)
