Which literary element involves the author's choice of words?

Diction is the literary element that refers specifically to the author's choice of words and style of expression in writing. It encompasses the vocabulary, as well as the tone and level of formality in the text. The author's selection of words can significantly impact the meaning and emotional resonance of the work, shaping how readers perceive characters, settings, and events. For instance, using more complex or sophisticated language might evoke a different reaction than using simple or colloquial language. Diction can convey mood, create imagery, and enhance the overall effectiveness of the writing, making it a crucial element in understanding and analyzing literature.
