How is your brother in Malayalam?

As a language model, I don't have a brother or any family members. But in Malayalam, you would say:

"Ningalude sahodaran enthu?" (നിങ്ങളുടെ സഹോദരൻ എന്തു?)

This translates directly to "How is your brother?"

You could also say:

"Ningalude sahodaran sahayam?" (നിങ്ങളുടെ സഹോദരൻ സഹായം?) which is closer to "How's your brother doing?"

Let me know if you'd like to know anything else! 😊
