A few part with a pound (7)
I believe the answer is:
several
'a few' is the definition.
(I've seen this before)
'part with a pound' is the wordplay.
'part' becomes 'sever' (severing is a kind of parting**).
'with' means one lot of letters go next to another.
'pound' becomes 'l'.
'sever'+'a'+'l'='SEVERAL'
(Other definitions for several that I've seen before include "A few; separate" , "quite a lot" , "A good few" , "Various, sundry" , "Indefinite number more than two or three, but not many" .)
