What does the term 'slang' refer to in language?

The term 'slang' refers to informal language that is often specific to a particular group, community, or context. Slang is characterized by its casual style and can change rapidly over time, reflecting the culture and trends of the group that uses it. It serves as a means of identity and can create a sense of belonging among its users.

In contrast, formal vocabulary typically refers to the more sophisticated, professional language used in academic or official contexts, which does not capture the essence of slang. The standard language used in writing aligns with grammatical norms and conventions, also diverging from the casual nature of slang. Technical terminology pertains to the specific language used within particular fields, which, while important, is distinctly different from the informal expressions indicative of slang.
