Whether you’re just pretending to understand certain Latin phrases, thinking about how Latin influenced Harry Potter, or pointing out Latin words hiding in plain sight, you probably know one thing for sure: Even if Latin is considered a dead language, it’s everywhere. And now, you can learn a little more of it on Duolingo, which partnered with the Paideia Institute—a non-profit that promotes the study and appreciation of classical language—to create its new Classical Latin course. Along the way, they also came up with new Latin words for decidedly modern things. Here are 14 of them you can add to the other Latin phrases you should be using.

  1. Telephonum gestabile: As you may have guessed from the telephonum bit, this phrase is Latin for cellphone. An app you’d use on your cell is programma.
  1. Pila electrica: If your telephonum gestabile suddenly dies, you can blame its pila electrica, or battery.
  1. Rete omnium gentium: You’re reading this on rete omnium gentium, or … the internet. If you want to specifically shout-out Wi-Fi, say aditus sine filo.
  1. Nubes: That place where you might back up your phone or store data—the cloud.
