It's gear possibly worn by bishops (7)
I believe the answer is:
gaiters
'worn by bishops' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe you can see a link between them that I don't see?
'it's gear possibly' is the wordplay.
'possibly' indicates an anagram.
'its'+'gear'='itsgear'
'itsgear' anagrammed gives 'GAITERS'.
Can you help me to learn more?
(Other definitions for gaiters that I've seen before include "things keeping mud off" , "Spats" , "Cloth coverings for legs - bishops may wear them" , "Protection for the legs" , "Legwear" .)
