Shed behind stable initially bolted (4)
I believe the answer is:
shut
'bolted' is the definition.
(I've seen this in another clue)
'shed behind stable initially' is the wordplay.
'shed' becomes 'hut' (I've seen this in another clue).
'behind' is a charade indicator (letters next to each other).
'initially' says to take the initial letters.
The initial letter of 'stable' is 's'.
'hut' after 's' is 'SHUT'.
(Other definitions for shut that I've seen before include "Close" , "Push to" , "Draw to" , "Out of business" , "not accepting visitors" .)
