magazine

I'm a little stuck... Click here to teach me more about this clue!

This could be a double definition.

'periodical' is the first definition.
(I know that Magazine is a type of periodical)

'explosive contents' is the second definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?

'with' is the link.

Can you help me to learn more?

(Other definitions for magazine that I've seen before include "Glossy publication?" , "Reading matter" , "Periodical - weapon store" , "Section of a firearm" , "Journal, periodical" .)
