When the writer uses complex words is diction informal?

No, when a writer uses complex words, their diction is not necessarily informal. In fact, the opposite is often true.

Here's why:

* Formal Diction: Formal diction is characterized by the use of complex, elevated vocabulary, often derived from Latin or Greek roots. It is typically found in academic writing, technical documents, speeches, and formal letters.

* Informal Diction: Informal diction uses simpler, everyday language, slang, and contractions. It is typical in casual conversations, personal letters, and fiction that aims to be relatable and conversational.

Example:

* Formal: "The protagonist's ambivalence towards his newfound wealth was palpable." (using complex words)

* Informal: "The guy was totally confused about being rich." (using simpler words)

Important Note:

* Diction is not simply about the complexity of individual words. It's about the *overall tone and style* created by word choice.

* A writer can use complex words in an informal way, creating a humorous or ironic effect.

* Conversely, a writer can use simple words in a formal way, creating a sense of clarity and directness.

In conclusion: Complex words alone do not determine whether diction is formal or informal. It's about the *context* and the *intended effect* of the language used.
