1. Structure:
* Informal Speech: Often lacks a strict structure, with sentences sometimes incomplete or fragmented. It may also include fillers like "um," "like," and "you know."
* Prose: Has a clear structure, with complete sentences, paragraphs, and often a specific organizational pattern (e.g., chronological order, cause and effect).
2. Vocabulary:
* Informal Speech: Uses colloquialisms, slang, and contractions (e.g., "gonna," "wanna"). May also be less precise in word choice.
* Prose: Employs a more formal vocabulary, avoiding slang and contractions. Word choice is carefully considered for clarity and impact.
3. Grammar:
* Informal Speech: May exhibit grammatical errors or deviations from standard grammar rules.
* Prose: Adheres to standard grammar rules and conventions. Sentences are typically grammatically correct and clear.
4. Purpose:
* Informal Speech: Often focused on immediate communication, conveying information or emotions in a spontaneous and conversational manner.
* Prose: Aims to communicate ideas, stories, or information in a structured and often persuasive or informative way. It is typically written for a broader audience.
It's important to remember that these are general guidelines, and there can be overlap and exceptions. The level of formality in both speech and prose can vary depending on the context, audience, and purpose.
