In court, throw off clothing here (6)
I believe the answer is:
closet
'clothing here' is the definition.
(place where clothing is stored)
'in court throw off' is the wordplay.
'in' indicates putting letters inside.
'court' becomes 'ct' (abbreviation used in road names).
'throw off' becomes 'lose' (to throw a game is to deliberately lose it. I am not sure about the 'off' bit.).
'ct' enclosing 'lose' is 'CLOSET'.
Can you help me to learn more?
(Other definitions for closet that I've seen before include "Study" , "place to store gear" , "A small room - best to come out of it" , "A small room - secret?" , "Small room or wardrobe" .)
