What type of literary device is this?
it is ~personification~ because a room is an inanimate object (is not human/cannot breathe or do human actions) so a room cannot literally roar...this must means that all of a sudden everyone in the room started to laugh, and the laughing was contagious hope i helped :)
What is the difference between a literary device and a rhetorical device?
I am confused about the two. What is the difference between them or are they the same thing? Please explain to me what they are, how they are different and their purpose. What are some examples of each? Any help is greatly appreciated.
What type of literary device is "My heart sank"?
"My heart sank" is personification, or describing a lifeless thing as doing something a living thing normally does. A heart can't literally sink in your body, but you (as a whole) can sink to your knees. I'd also like to add that a metaphor is a comparison between two objects and the heart is not being compared to anything. For it to be a metaphor, it would have to include a another object to be compared to. For example: "My heart sank lower than the Titanic after it hit the iceberg." Here, the heart is compared to the Titanic and can be considered a metaphor.
What's this literary device called?
It's a metaphor, because it says that there ARE butterflies in that person's stomach when there clearly aren't. If it had said 'It feels like there are butterflies in my stomach', that would be a simile. It could also be referred to as an idiom, which is basically a fancy word for a figure of speech, because it is a phrase that is commonly used and it is not taken literally. You know what it means when you hear it.
