Rough turn following current former wife (7)
I believe the answer is:
inexact
'rough' is the definition.
('inexact' can be similar in meaning to 'rough')
'turn following current former wife' is the wordplay.
'turn' becomes 'act' (theatre).
'following' is a charade indicator (letters next to each other).
'current' becomes 'in' (I've seen this in other clues**).
'former wife' becomes 'ex'.
'in'+'ex'='inex'
'act' after 'inex' is 'INEXACT'.
(Other definitions for inexact that I've seen before include "Imprecise - inaccurate in" , "Woolly" , "Nice tax (nag.)" , "loose" , "Fuzzy, muddled" .)
