Diction refers to the choice of words and phrases in speech or writing. It encompasses a writer's or speaker's vocabulary, style of expression, and the connotations of the words they use. Diction can be formal, informal, colloquial, or slang, depending on the tone and context of the communication.
In literature, diction is an important aspect because it can affect the mood, tone, and meaning of a text. For example, elevated diction might convey a sense of seriousness or formality, while informal diction might create a more relaxed or casual tone. Writers often use specific diction to convey character, set a scene, or evoke emotions.
Overall, diction plays a crucial role in how effectively a message is communicated and how it resonates with the audience.
