A bit of violence in the borders of Bangladesh (4)
I believe the answer is:
bash
'a bit of violence' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'borders of bangladesh' is the wordplay.
'borders of' suggests removing the centre.
'bangladesh' with its centre taken out is 'BASH'.
'in the' is the link.
Can you help me to learn more?
(Other definitions for bash that I've seen before include "Strike hard; party" , "Smite; a party" , "Strike violently" , "Party; attempt (slang)" , "Heavy blow; party" .)
