How do you write hello in Malayalam?

There are two common ways to say "hello" in Malayalam, depending on the context and level of formality:

Informal:

* ഹലോ (Halo) - This is the most common way to say hello in casual conversation. It's a direct transliteration of the English word "hello."

Formal:

* നമസ്‌തേ (Namaste) - This is a more respectful greeting, literally meaning "I bow to you." It's used in formal situations or when addressing someone you respect.

You can also use other greetings, such as:

* ശുഭോദയം (Shubhodhayam) - Good morning

* നന്മകൾ (Nammakal) - Good afternoon/good evening

The choice of greeting depends on the situation and your relationship with the person you are addressing.
