Learn French: Le reportage dont il s'agit révèle un grand scandale. - The news report in question reveals a big scandal.

The expression il s'agit de means "it is about" or "it is a matter of". When you combine it with the relative pronoun dont (which replaces phrases starting with de), the literal meaning is "about which it is a matter". In natural English, we say the report "in question" or the report "that we are talking about".

Why do we use dont instead of que to say "that" or "which"?

The pronoun dont is required because it replaces phrases that use the preposition de. Since the fixed expression is il s'agit de, we need dont to connect it back to le reportage. If you used que, the essential de from the expression would be missing.

Does un reportage mean the same thing as a work or school report?

Not quite! The word un reportage specifically refers to a piece of journalism, like a news broadcast or a media article. If you need to talk about a business, financial, or academic report, you should use the word un rapport.

Why does the adjective grand come before scandale?
