Sign off after concealed beatings (7)
I believe the answer is:
hidings
'beatings' is the definition.
(I've seen this before)
'sign off after concealed' is the wordplay.
'off' indicates anagramming the letters.
'after' is a charade indicator (letters next to each other).
'concealed' becomes 'hid' (I've seen this before**).
'sign' is an anagram of 'ings'.
'ings' put after 'hid' is 'HIDINGS'.
(Other definitions for hidings that I've seen before include "Beatings" , "concealed?" .)
