Len has consumed some more fruit! (5)
I believe the answer is:
lemon
'fruit' is the definition.
(lemon is a kind of fruit)
'len has consumed some more' is the wordplay.
'len has' becomes 'leon' (I can't explain this - if you can you should believe this answer much more).
'consumed' means one lot of letters goes inside another.
'some more' becomes 'm'.
'leon' enclosing 'm' is 'LEMON'.
Can you help me to learn more?
(Other definitions for lemon that I've seen before include "Fruit - useless thing" , "certainly not a plum!" , "Fruit (which is proverbially "the answer")" , "something unattractive" , "Defective object" .)
