Look around the empty place (6)
I believe the answer is:
locate
'place' is the definition.
(synonyms)
'look around the empty' is the wordplay.
'look' becomes 'lo' (archaic exclamation meaning 'look!').
'around' becomes 'ca' (circa).
'empty' suggests removing the centre.
'the' with its middle taken out is 'te'.
'lo'+'ca'+'te'='LOCATE'
(Other definitions for locate that I've seen before include "Discover place where thing is" , "Fix position of" , "Find, or establish in particular place" , "Lay one's hands on (something)" , "Find or situate" .)
