I know the two can overlap, but to me they're distinct. I've always defined exposition as "repeating what the reader already knows", whereas infodumping is just "giving information in huge chunks of text". But I've also seen "exposition" used as a synonym for "backstory that's important to the present plot", which kind of confused me, since the reader wouldn't necessarily know that backstory beforehand. How do you guys define each of them?
