Walk around large venue (5)
I believe the answer is:
place
'venue' is the definition.
(I've seen this before)
'walk around large' is the wordplay.
'walk' becomes 'pace' (pacing is a kind of walking).
'around' indicates putting letters inside.
'large' becomes 'l'.
'pace' placed around 'l' is 'PLACE'.
(Other definitions for place that I've seen before include "Spot" , "Locus" , "Locate" , "Endearingly pretty" , "Location; put" .)
