Soak vessel and put back (6)
I believe the answer is:
return
'put back' is the definition.
(thesaurus)
'soak vessel' is the wordplay.
'soak' becomes 'ret' (ret can mean to soak in water).
'vessel' becomes 'urn' (urn is a kind of vessel).
'ret'+'urn'='RETURN'
'and' acts as a link.
(Other definitions for return that I've seen before include "Come back with financial statement" , "Take back" , "hit back?" , "Profit earned on money" , "answer" .)
