Ran back to argue, being limited (6)
I believe the answer is:
narrow
'being limited' is the definition.
(associated in meaning)
'ran back to argue' is the wordplay.
'back' is a reversal indicator.
'to argue' becomes 'row' (to row with someone is to argue with them).
'ran' written backwards gives 'nar'.
'nar'+'row'='NARROW'
(Other definitions for narrow that I've seen before include "... not one" , "Cramped" , "Circumscribed" , "Restricted in width." , "Strait, not wide" .)
