What year was slang invented?

Slang wasn't "invented" in a specific year. It's a constantly evolving aspect of language that has existed for as long as people have spoken.

Here's why:

* Slang is inherently dynamic: It changes with time, social groups, and cultural shifts. What's considered slang today might be obsolete tomorrow.

* Slang is rooted in everyday speech: People have always used informal language, jargon, and code words to express themselves, especially within specific communities.

While we can't pinpoint a specific year, we can find examples of slang throughout history:

* Ancient Greek and Roman slang: Examples of slang terms have been documented in literature and historical texts from these periods.

* Medieval slang: Words and phrases used by different social classes and guilds emerged during this era.

* Modern slang: The explosion of mass media, technology, and global communication has fueled a rapid evolution of slang in recent decades.

So, rather than trying to find a specific year of invention, it's more accurate to view slang as a continuous process of language development and adaptation.
