Near front of tall cupboard (6)
I believe the answer is:
closet
'cupboard' is the definition.
(type of cupboard)
'near front of tall' is the wordplay.
'near' becomes 'close' (synonyms).
'front of' suggests taking the first letters.
The first letter of 'tall' is 't'.
'close'+'t'='CLOSET'
(Other definitions for closet that I've seen before include "A small room - best to come out of it" , "Small room or cabinet for storage" , "Cupboard (to come out of)" , "A small room - secret?" , "little room" .)
