Identify and explain the figurative language used in these lines "I was nothing but a body. Perhaps even less:a famished stomach. The stomach alone was measuring time" (Quote from "Night" by Elie Wiesel)

Metonymy

Metonymy is a literary device where a part of something stands in for the whole. In this case, Elie is using his stomach to represent all of him. It's not quite a metaphor because the stomach is part of him already, but it is standing alone to reference how he is feeling.
