Iron in cupboard (5)
I believe the answer is:
press
I believe this is a double definition.
'iron' is the first definition.
(thesaurus)
'cupboard' is the second definition.
(thesaurus)
'in' acts as a link.
(Other definitions for press that I've seen before include "flock" , "Push - papers" , "Squeeze out (juice/oil)" , "somewhere to keep clothes" , "Crowd; urge" .)
