Question

How can I write an effective outline for an essay?

Answer 1

What kind of essay are you writing?

Answer 2

For a persuasive essay, I've always been told to state my opinion, give a reason, explain, then conclude my opinion in the most simplistic way possible. Then go in and add depth.
For an informative essay, just state your introduction, then write a topic sentence for each paragraph you need to write.
And for a narrative essay, (in my opinion, the easiest and most fun) You pretty much just create a storyline, with beginning, middle, and end.
Hope this helped and good luck!
