Final answer:
Hyperbole contributes to the overall meaning of a poem by creating emphasis, exaggeration, and vivid imagery.
Step-by-step explanation:
Hyperbole contributes to the overall meaning of a poem by creating emphasis, exaggeration, and vivid imagery. It helps to convey intense emotions, capture attention, and make a lasting impact on the reader. For example, in the line 'I'm so hungry I can eat a horse,' the hyperbole emphasizes extreme hunger and creates a strong visual image in the reader's mind. By using hyperbole, poets can heighten the impact and significance of their words.
