Here's a breakdown:
* Langue: This represents the underlying structure of a language, including its grammar, vocabulary, and rules. It's the idealized system that everyone who speaks that language should theoretically be able to understand.
* Parole: This is the concrete realization of language. It's how individuals actually speak, write, and use language in everyday life. It includes variations in pronunciation, vocabulary, sentence structure, and overall style based on context, speaker, and other factors.
Think of it this way:
* Langue is like the blueprint for building a house. It outlines the basic design and structure.
* Parole is like the actual house built from that blueprint. It might have unique features, variations in materials, and specific decorations that make it different from other houses built from the same blueprint.
Examples of parole:
* A casual conversation with friends uses different vocabulary and grammar than a formal presentation at work.
* A news report uses a more structured and objective language than a personal blog post.
* The way you speak to your grandmother might be different from how you speak to your best friend.
In essence, parole is the "live" and ever-changing use of language, while langue is the "static" and idealized system. The interplay between these two concepts is essential for understanding the complexities of language and communication.
