I am not fully sure if this is the right place for this question but I am guessing has something to do with structure and usage so hopefully it is alright here. Apologies if not.
I am getting confused when I write long reports and essays about when I should be writing paragraphs with a space separating and when I should have them following one another without a space.
I have been putting a space when it looks like too much of a wall of text but I am finding that paragraphs without spaces between them, look a bit weird.
Is it just when you start talking about something completely different that you should put a space, or should they follow on, too? Should the space even be there or is it just something people do?
