Gate there dangling -- not entirely fixed (8)
I believe the answer is:
tethered
'fixed' is the definition.
(thesaurus)
'gate there dangling not entirely' is the wordplay.
'not entirely' says the answer is hidden in the clue.
'TETHERED' is hidden in the letters of 'gate there dangling'.
(Other definitions for tethered that I've seen before include "Tied (animals) up" , "Of animal, with rope fastened to prevent straying" , "Tied to something with a rope" , "Confined in range by tied rope" , "Restrained with a rope" .)
