Get up and is about to go round (4)
I believe the answer is:
rise
'get up' is the definition.
('rise' can be a synonym of 'get up')
'is about to go round' is the wordplay.
'about' becomes 're' (regarding).
'to go round' means one lot of letters goes inside another.
'is' going into 're' is 'RISE'.
'and' is the link.
(Other definitions for rise that I've seen before include "Salary increase" , "more money" , "Soar" , "To swell (bread)" , "Hill" .)
