This question is related to “A Good Man is Hard to Find” by Flannery O’Connor.
Answer and Explanation:
Diction is the term that refers to the choice and structuring of words in a text, with the objective of changing a language according to the objective intended by the author. In "A good man is hard to find", we can see that the author decided to use informal words, slang, colloquial expressions and a simpler and more direct language. Thus, we can conclude that the author used a colloquial diction.
This diction allows the author to create a more intimate and comfortable connection with the reader, since the text is less pretentious and more accessible to anyone who wishes to enter this language.
The text has no neoclassical poetic diction.
