Near to top cabinet (6)
I believe the answer is:
closet
'cabinet' is the definition.
(I've seen this before)
'near to top' is the wordplay.
'near' becomes 'close' (synonyms).
'to top' becomes 't' (I can't justify this - if you can you should believe this answer much more).
'close'+'t'='CLOSET'
Can you help me to learn more?
(Other definitions for closet that I've seen before include "Shut away in private conference - in small room?" , "Secret - cupboard" , "Small cupboard or recess" , "A small room - best to come out of it" , "Furtive" .)
