If you have young people in your life, you might've heard them use words such as skibidi (SKIH-bih-dee) or rizz or sigma. Maybe that's mumbo-jumbo to you, as mumbo-jumbo was to someone else in the past. But Adam Aleksic says that's just how language evolves. And as we continue through the internet age — specifically the era of short form video — the rate of change in our language is only going to accelerate. Aleksic, known online as @EtymologyNerd, writes about this in his new book, Algospeak: How Social Media Is Transforming the Future of Language.
