Cupboard the tennis racket's in? (5)
I believe the answer is:
press
'cupboard' is the definition.
(term for a large cupboard)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for press that I've seen before include "harass > crowd" , "somewhere to keep clothes" , "Smooth" , "Produce record" , "Harass; media" .)
