Bar is evacuated, after evacuation it’s limited (9)
I believe the answer is:
localised
'limited' is the definition.
(localising is a kind of limiting)
'bar is evacuated after evacuation' is the wordplay.
'bar' becomes 'local' (I've seen this before).
'evacuated after evacuation' becomes 'ed' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'local'+'is'+'ed'='LOCALISED'
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for localised that I've seen before include "specific area" , "constrained?" , "in a particular place" .)
