Yes, ‘scared to death’ is indeed a metaphor. This expression is often used to describe a state of extreme fear or fright. The phrase does not literally mean that someone has died from fear; rather, it conveys the intensity of the emotion experienced in a particular moment.
Metaphors are figures of speech that make comparisons between unrelated things to highlight specific qualities or experiences. In this case, ‘scared to death’ emphasizes how overwhelming fear can feel, as if it could lead to a fatal outcome. It’s a vivid way to communicate strong feelings, making it easier for others to understand the level of anxiety or concern someone is experiencing.
