One might be tucked in a paper clip (8)
I believe the answer is:
magazine
'clip' is the definition.
(I know that clip can be written as magazine)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for magazine that I've seen before include "Periodical publication" , "Section of a firearm" , "Weapons' store" , "Slug container" , "What holds cartridge" .)
