Banish from glorious twelfth (4)
I believe the answer is:
oust
'banish' is the definition.
(I've seen this in another clue)
'from glorious twelfth' is the wordplay.
'from' indicates a hidden word.
'OUST' can be found hidden inside 'glorious twelfth'.
(Other definitions for oust that I've seen before include "Force from office" , "Remove or reject from position" , "Expel (from a place)" , "Overthrow" , "Show the door to" .)
