سُيُوفًا تَلْمَعُ ... وَصَاعِقَةٌ مِنْ نَصْلِهِ
“Gleaming swords ... and a thunderbolt from his blade,” a martial image.
Expressions such as “swords,” “gleam,” “thunderbolt” and “blade” reinforce one another. Linking a sword's flash to lightning suggests brilliance and force, yet the image cannot always be interpreted adequately by isolating only one word.
The analytic task is not merely to call unusual language beautiful. It is to establish the borrowed expression, its original referent, the feature that motivates the transfer, and the contextual evidence that differentiates literal and figurative readings.
