Sprinted back to argue, being restricted (6)
I believe the answer is:
narrow
'being restricted' is the definition.
(I've seen this before)
'sprinted back to argue' is the wordplay.
'sprinted' becomes 'ran' (I've seen this before).
'back' says the letters should be written in reverse.
'to argue' becomes 'row' (to row with someone is to argue with them).
'ran' in reverse letter order is 'nar'.
'nar'+'row'='NARROW'
(Other definitions for narrow that I've seen before include "Small in breadth" , "Circumscribed" , "Vessel designed for canals" , "Strait or confined" , "Thin; taper" .)
