Perhaps give knife to a boy to cut through half of meat spread (9)
I believe the answer is:
marmalade
'half of meat spread' is the definition.
'marmalade' can be an answer for 'spread' (I've seen this before). I am not sure about the 'half of meat' bit.
'perhaps give knife to a boy to cut' is the wordplay.
'perhaps' becomes 'made' (I can't justify this - if you can you should give a lot more credence to this answer).
'give' is a charade indicator (letters next to each other).
'knife' becomes 'arm' (knife is an example).
'to a boy' becomes 'Al'.
'to cut' means one lot of letters goes inside another (some letters have cut into others).
'arm' put next to 'al' is 'armal'.
'made' going around 'armal' is 'MARMALADE'.
'through' acts as a link.
Can you help me to learn more?
(Other definitions for marmalade that I've seen before include "Orange jam" , "Orange conserve" , "Orange preserve" , "confiture" , "Jame made from citrus fruits" .)
