Little piece of paper attached to loafer? (4-2)
I believe the answer is:
slip-on
'loafer?' is the definition.
(I've seen this in another clue)
'little piece of paper attached to' is the wordplay.
'little' means to remove the last letter (the word is not quite complete).
'piece of paper' becomes 'slip' (slip is a kind of piece of paper).
'attached to' becomes 'pon' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'slip' with its final letter taken away is 'sli'.
'sli'+'pon'='SLIP-ON'
Can you help me to learn more?
(Other definitions for slip-on that I've seen before include "Shoe without fasteners" , "Shoe, not a 10" , "Without fastening" , "Not a lace-up" , "Garment or shoe with little or no fastening" .)
