Hung about corner in dead-ends (7)
I believe the answer is:
dangled
'hung' is the definition.
(dangling is a kind of hanging)
'corner in dead-ends' is the wordplay.
'corner' becomes 'angle' (I've seen this in another clue).
'in' indicates putting letters inside.
'ends' suggests removing the centre.
'dead' with its centre taken out is 'dd'.
'angle' going into 'dd' is 'DANGLED'.
'about' acts as a link.
(Other definitions for dangled that I've seen before include "suspended" , "Hung" , "was on gibbet?" .)
