Purchase method showing masculine neatness, say (4,5)
I believe the answer is:
mail order
'purchase method' is the definition.
'mail-order' can be an answer for 'purchase' (type of purchase). I am unsure of the 'method' bit.
'masculine neatness say' is the wordplay.
'masculine' becomes 'mail' (I can't explain this - if you can you should give a lot more credence to this answer).
'neatness say' becomes 'order' (neatness is a kind of order).
'mail'+'order'='MAIL-ORDER'
'showing' acts as a link.
Can you help me to learn more?
(Other definitions for mail order that I've seen before include "Buying by post" , "postal application for goods" , "type of catalogue" , "purchased by post" , "Type of purchase" .)
