Ok so I am doing a comic(manga) for a contest and I have to not use dialogue or sound effects. So if my characters wrote something down, would it be considered dialogue? I know they can't talk, but I want to know if them writing something down would be considered dialogue. As in the writing itself.
The Greek word "dia-" means across or through or between. Like diameter is across the circle, a doctor's diagnosis is through knowledge, and dialogue is between two people. So writing instead of talking is still dialogue.
You might want to take a year of Latin so you will realize that about half of every language in Europe is derived from it. If you read the bible, you need at least a little bit of Greek.
You need to read novels. Lots of novels. Any novels. Notice that they all have perfect spelling, perfect punctuation, perfect composition. Notice where they use one space and where they use two. Notice that every speaker in a dialog gets a new paragraph, and every paragraph is preceded by a blank line. Notice any writing techniques or figures of speech. Take notes so you know where you found what you know. It takes a lot of reading to be a writer.
