I noticed that the Latin word deus and the Telugu word దేవుడు (dēvuḍu) sounded sort of similar. I wondered if they were somehow related, since even though Telugu is Dravidian, it does take a lot of influence from Sanskrit, which, along with Latin, is Indo-European. It turns out that they’re related.

Proto-Indo-European has the word deywós, meaning god.

• In Proto-Indo-Iranian, that becomes daywás. Sanskrit makes it देव (devá). I’m not sure if it ever reached Proto-Dravidian, but it did reach Telugu and Tamil (both being ancestors of Proto-Dravidian).
• In Proto-Italic, it becomes deiwos. In Old Latin, it’s deivos, which becomes deus in Latin.
