Haggard permitted to take glove (8)
I believe the answer is:
gauntlet
'glove' is the definition.
(gauntlet is a kind of glove)
'haggard permitted' is the wordplay.
'haggard' becomes 'gaunt' ('gaunt' can be a synonym of 'haggard').
'permitted' becomes 'let' (I've seen this before).
'gaunt'+'let'='GAUNTLET'
'to take' is the link.
(Other definitions for gauntlet that I've seen before include "Strong glove, thrown down in challenge" , "Stout glove" , "Metal glove of medieval soldiers" , "Knight's glove" , "Iron glove" .)
