The first line, because dialect in literature means a form of writing that shows the accent and way people talk. Because of the definition where it says “might ‘a’ thought” is dialect.
I believe the term is Syntax.
Movie people are able to write up how they want a scene to look like, then they can use things like backgrounds and crops to make a visual representation of how they want their scene to look like. Authors don't have things like props and backgrounds, so they have to put a lot of detail into their writing for readers to visualize.
