Removing or securing piece of paper (8)
I believe the answer is:
clipping
'piece of paper' is the definition.
'clipping' can be an answer for 'piece' (thesaurus). I am not certain of the 'of paper' bit.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for clipping that I've seen before include "Cutting (from a newspaper?)" , "Striking sharply" .)
