Covering a friend needing money (4)
I believe the answer is:
pall
'covering' is the definition.
(pall is a kind of covering)
'a friend needing money' is the wordplay.
'a friend' becomes 'pal' (pal is a kind of friend).
'needing' says to put letters next to each other.
'money' becomes 'l' (L can mean 'pounds').
'pal'+'l'='PALL'
(Other definitions for pall that I've seen before include "Cloth spread over a coffin" , "tedious here" , "Cloth to cover a coffin" , "Become less appealing" , "A dark cover; cease to interest" .)
