Doctor sorry in Wilts (6)
I believe the answer is:
droops
'wilts' is the definition.
('droop' can be a synonym of 'wilt')
'doctor sorry' is the wordplay.
'doctor' becomes 'dr' (abbreviation).
'sorry' becomes 'oops' (I've seen this in another clue).
'dr'+'oops'='DROOPS'
'in' acts as a link.
(Other definitions for droops that I've seen before include "Hangs limply down" , "'Sags, wilts (6)'" , "Grows weak and hangs down" , "Languishes" , "Hangs loosely or laxly" .)
