Regularly repairing pocket (4)
I believe the answer is:
earn
'pocket' is the definition.
(I've seen this in another clue)
'regularly repairing' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The alternate letters of 'repairing' are 'EARN'.
(Other definitions for earn that I've seen before include "Receive in return for" , "Gain by effort (4)" , "Make - merit" , "Win" , "Be paid for work" .)
