There are a few ways to say "hello" in Tamil, depending on the context and level of formality. Here are a few options:

Formal:

* வணக்கம் (Vanakkam): This is the most common and polite greeting, used in formal settings like meetings and when addressing elders. It literally translates to "respect" or "greetings."

* சல்யூட் (Salute): This is a more formal greeting borrowed from English and is used in military contexts.
