* Slang is constantly evolving: It changes rapidly, often disappearing as quickly as it appears. Standard English, while it can adapt, is much more stable.
* Slang is specific to groups: It's often used within specific communities, age groups, or social circles. Standard English, on the other hand, is intended to be understood by a broader audience.
* Slang is often playful: It can be used for humor, emphasis, or to create a sense of belonging. Standard English is typically more formal and intended for clear communication.
Think of it this way:
* Standard English is like a formal dictionary: It contains the accepted words and grammar of the language.
* Slang is like a specialized dictionary: It contains words and phrases used in specific groups or contexts, and may change over time.
So, while slang is informal, it's more accurately described as a separate system of language, rather than just an informal variety of standard English.
