Time to circle round as well (3)
I believe the answer is:
too
'as well' is the definition.
(both can mean 'also')
'time to circle round' is the wordplay.
'time' becomes 't' (abbreviation).
'to circle' becomes 'O' (O is a circle).
'round' becomes 'o' (round can mean a round object).
't'+'o'+'o'='TOO'
(Other definitions for too that I've seen before include "Furthermore" , "Also; overly" , "As well, also" , "What a pity!" , "Moreover, in addition" .)
