There are five types of imagery that appeal to the different senses: visual, auditory, olfactory, gustatory, and tactile. Imagery creates vivid descriptions that help readers visualize scenes. Authors use imagery for various purposes like setting mood, aiding the imagination, or beautifying literature.
Diction refers to word choice and there are different levels and styles of diction. Formal diction uses sophisticated language while informal diction is more conversational. Abstract diction describes intangible ideas while concrete diction provides specific details. Diction also has denotation versus connotation and is shaped by factors like subject, purpose, audience, and occasion. Effective diction uses precise language to clearly convey meaning and establish tone.
