What figurative language is he knew pursuer was coming?

This sentence doesn't contain any figurative language. It's a straightforward statement using literal language.

To identify figurative language, look for:

* Metaphor: A comparison between two unlike things without using "like" or "as" (e.g., "He was a lion in battle.")

* Simile: A comparison between two unlike things using "like" or "as" (e.g., "She ran like a cheetah.")

* Personification: Giving human qualities to inanimate objects or animals (e.g., "The wind whispered secrets.")

* Hyperbole: An exaggeration (e.g., "I'm so hungry I could eat a horse.")

* Understatement: A statement that minimizes the importance of something (e.g., "I'm a little bit tired" after running a marathon.)

None of these devices are present in the sentence "He knew his pursuer was coming."
