Ben and Leon working for raise (7)
I believe the answer is:
ennoble
'for raise' is the definition.
(I've seen this before)
'ben and leon working' is the wordplay.
'and' says to put letters next to each other.
'working' is an anagram indicator.
'ben' put after 'leon' is 'leonben'.
'leonben' anagrammed gives 'ENNOBLE'.
(Other definitions for ennoble that I've seen before include "Raise to the knighthood or make more dignified" , "Elevate to peerage" , "Raise to the aristocracy" , "Exalt" , "Make a peer" .)
