Run out, as a subscription (5)
I believe the answer is:
lapse
'run out as a subscription' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lapse that I've seen before include "Pleas (anag)" , "Go back to bad behaviour" , "unguarded moment" , "Retrogress" , "Slip-up" .)
