Around a round (5)

I believe the answer is:

about

'around' is the definition.
(synonyms)

'a round' is the wordplay.
'round' becomes 'bout' (synonyms).
'a'+'bout'='ABOUT'

(Other definitions for about that I've seen before include "nearby" , "Almost; around" , "Regarding" , "Approximately, around" , "Not exactly - concerning" .)

I've seen this clue in the Evening Standard.
