Wasting time, overlook securing European capital for operations on paper (7)
I believe the answer is:
origami
'operations on paper' is the definition.
'origami' can be an answer for 'operations' (I have seen 'Delicate operations' mean 'origami' so perhaps 'operations' could also mean 'origami'). I also know that 'paper' relates to this answer.
'wasting time overlook securing european capital' is the wordplay.
'wasting time' becomes 'imo' (I can't explain this - if you can you should give a lot more credence to this answer).
'overlook' shows that the letters should be reversed in order (I've seen 'overlooked' mean this).
'securing' means one lot of letters goes inside another.
'european capital' becomes 'riga' (capital of Latvia).
'imo' backwards is 'omi'.
'omi' going around 'riga' is 'ORIGAMI'.
'for' is the link.
Can you help me to learn more?
(Other definitions for origami that I've seen before include "Paperwork, as it were" , "The folding of sheets" , "Delicate operations" , "US record label" , "It's crafty folding" .)
