Is slang considered as colloquial words?

Yes, slang is generally considered a subset of colloquial words.

Here's why:

* Colloquialisms are words or phrases that are used in informal speech and writing. They are typically specific to a region or social group.

* Slang is a type of colloquialism that is informal and often used within a particular group of people. It is often short-lived and can change rapidly.

Therefore, all slang is colloquial, but not all colloquialisms are slang.

For example:

* Colloquial: "Y'all" (Southern US)

* Slang: "Lit" (meaning exciting or fun)

Both "y'all" and "lit" are informal and used in specific contexts, making them colloquial. However, "lit" is considered slang because it is more informal and short-lived than "y'all."
