Body time, roughly (5)
I believe the answer is:
torso
'body' is the definition.
('torso' can be a synonym of 'body')
'time roughly' is the wordplay.
'time' becomes 't'.
'roughly' becomes 'orso' ('or so' can be a synonym of 'roughly').
't'+'orso'='TORSO'
(Other definitions for torso that I've seen before include "Roots (anag)" , "Body without head, neck and limbs" , "Trunk, something unfinished" , "Body (excluding head, neck and limbs)" , "Body's trunk" .)
