What is the definition of concrete diction?

CONCRETE DICTION- Language that describes qualities that can be perceived with the five senses as opposed to using abstract or generalized language. For instance, calling a fruit "pleasant" or "good" is abstract, while calling a fruit "cool" or "sweet" is concrete. The preference for abstract or concrete imagery varies from century to century. Philip Sidney praised concrete imagery in poetry in his 1595 treatise, Apologie for Poetrie. A century later, Neoclical thought tended to value the generality of abstract thought. In the early 1800s, the Romantic poets like Wordsworth, Coleridge, and Shelley once again preferred concreteness. In the 20th century, the distinction between concrete and abstract has been a subject of some debate. Ezra Pound and T. E. Hulme attempted to create a theory of concrete poetry. T. S. Eliot added to this school of thought with his theory of the "objective correlative." Contrast with abstract diction / abstract imagery.
