How do you say hello in Dravidian?

There is no single "Dravidian" language. Dravidian is a language family, like Indo-European, and encompasses many languages. To say "hello" in a Dravidian language, you need to specify which language you want.

Here are some examples:

* Tamil: Vanakkam (வணக்கம்)

* Malayalam: Namaskaram (നമസ്കാരം)

* Telugu: Namaskaram (నమస్కారం)

* Kannada: Namaskara (ನಮಸ್ಕಾರ)

* Tulu: Namaskara (ನಮಸ್ಕಾರ)

* Kodava: Namaskara (ನಮಸ್ಕಾರ)

Let me know which Dravidian language you are interested in, and I can give you the specific greeting.
