Bound for the cellar (5)
I believe the answer is:
vault
I believe this clue is a double definition.
'bound' is the first definition.
(thesaurus)
'the cellar' is the second definition.
(thesaurus)
'for' acts as a link.
(Other definitions for vault that I've seen before include "Where bodies may be kept" , "Secure room -- spring over" , "Leap - wine or money chamber?" , "bound?" , "Strongroom or burial chamber" .)
