Final answer:
The literary device in the sentence 'Clemont was turned to stone' is a metaphor because it directly compares Clemont's state to that of a stone without using 'like' or 'as', suggesting he is immobile or emotionally unresponsive.
Step-by-step explanation:
In the sentence “Clemont was turned to stone,” the literary device being used is a metaphor. Unlike a simile, which makes a comparison using the words “like” or “as,” a metaphor states that one thing is something else, implying a direct comparison without using such words. In this case, Clemont isn’t literally turned into stone, but the phrase suggests a strong similarity between Clemont's state and being a statue, possibly meaning he is immobile or emotionally unresponsive. It’s not a simile, because it doesn’t use “like” or “as”; it’s not personification, as it doesn’t give human characteristics to a non-human subject; and it’s not hyperbole, as it doesn’t exaggerate the statement to an extreme level. Metaphors are a form of figurative language that convey meaning by implying a likeness between two different things, which is what this sentence does by comparing Clemont to stone.
