What type of figurative language is used in the statement "I am so tired I could sleep for a year?"

The statement "I am so tired I could sleep for a year" exemplifies hyperbole, which is a form of figurative language that involves exaggerated statements not meant to be taken literally. Hyperbole is used to emphasize the intensity of a feeling or situation, in this case, the speaker's level of tiredness. By claiming they could sleep for an entire year, the speaker dramatically illustrates their exhaustion, highlighting how overwhelming their tiredness feels without intending it to be a literal truth.

In contrast, metaphor involves comparing two unrelated things directly without using "like" or "as," simile makes such comparisons using "like" or "as," and personification attributes human characteristics to non-human entities. None of these other types of figurative language apply to the statement, as it focuses purely on an extreme exaggeration to stress the speaker's fatigue.
