Thanks, Angela. Does that mean when you submit your work, that you underline thoughts, as well as using, italics or just one of them, (unless you say, I thought.)
Sorry, I'm a bit thick sometimes.
First, it's important to point out that some people use italics for thoughts in a story, others do not. It depends on the narrative distance you're going for. If the distance is quite close (the narrative and inner thoughts/dialogue almost become one with no real way to discern where narrative ends and internal thought begins), then you likely wouldn't italicize at all. However, if your narrative distance is further apart from your character and his or her internal thoughts/dialogue, you may wish to use italics. This is
only if you are not using a thought tag (he thought, he wondered, etc).
So, if it is:
I hope the teacher doesn't ask me, I thought.
then no italics in your story.
If it is:
I hope the teacher doesn't ask me.
and there's a definite line between narrative and thought, you'd use italics (IMO.)
So in a submission format, you'd underline
I hope the teacher doesn't ask me to show it as italics. There is no need to use both italics and underline in submission format to 'show' that something should be in italics.
This is how I have sent my MS, and there has been no concerns over the format from my agent or the editors viewing my work. I hope this helps!
