1. Identify the abstract concept: The phrase implies fear or cowardice.
2. Choose an abstract noun: You could use:
* Fear: "Fear propelled his flight."
* Cowardice: "Cowardice drove him to flee."
* Terror: "Terror compelled his escape."
3. Reword the sentence:
* "Fear propelled his flight."
* "Cowardice drove him to flee."
* "Terror compelled his escape."
Explanation:
* Fear, cowardice, and terror are all abstract nouns representing intangible feelings or qualities.
* By replacing the concrete phrase "the coward fled" with these abstract nouns, you emphasize the emotional state driving the action.
