Make out, when you minister to beforehand (7)
I believe the answer is:
pretend
'make out' is the definition.
(I've seen this before)
'minister to beforehand' is the wordplay.
'minister' becomes 'tend' (I've seen this in another clue).
'to' means one lot of letters go next to another (I've seen this in other clues).
'beforehand' becomes 'pre' (I can't justify this - if you can you should give a lot more credence to this answer).
'tend' after 'pre' is 'PRETEND'.
'when you' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for pretend that I've seen before include "Simulate, feign" , "Simulated" , "Make believe - imply falsely" , "Imaginary, make-believe" , "Behave unnaturally" .)
