Shares the soup (5)
I believe the answer is:
stock
I believe this clue is a double definition.
'shares' is the first definition.
(thesaurus)
'soup' is the second definition.
(stock is a kind of soup)
'the' acts as a link.
(Other definitions for stock that I've seen before include "soup ingredient" , "Equestrian tie" , "Consomm-like liquid" , "Wares" , "Neck adornment" .)
