Bloke protecting appendage that's worn (7)
I believe the answer is:
garment
'that's worn' is the definition.
I can't tell whether this definition defines the answer.
'bloke protecting appendage' is the wordplay.
'bloke' becomes 'gent' (I've seen this before).
'protecting' indicates putting letters inside (inserted letters are held or protected).
'appendage' becomes 'arm' (arm is a kind of appendage).
'gent' enclosing 'arm' is 'GARMENT'.
Can you help me to learn more?
(Other definitions for garment that I've seen before include "An article of clothing (7)" , "Something put on" , "coat maybe" , "Grant me (anag.)" , "Raiment" .)
