Languages are primarily created and evolved by teenagers. It’s always been this way. Each new generation finds new ways of contextualizing the world, and new ways of explaining aspects of it. Teenagers create tons of new experimental words. Most have short half-lives and peter out over time. Some turn out to be genuinely linguistically useful and survive the test of time.

It’s a safe bet that the vast majority of words you use on a daily basis were first uttered by a teenager somewhere in the recent or distant past.

Language evolves through teens.
