Do it for me: verb + giùm / hộ

In Saigon, giùm after a verb turns it into a favour, like "for me" or "would you": Anh mở cửa giùm em nha. Could you open the door for me? It's friendly and very common, the everyday way to ask someone to do something small.

It goes after the verb, and the person you're helping can follow: chụp giùm tụi em tấm hình, take a photo for us. The thing can come before or after it: cầm giùm chị cái túi and cầm cái túi giùm chị both work. Ending with được không makes a polite question: Anh chụp giùm tụi em tấm hình được không?

Giúp works the same way and is neutral; it's the one you'll see written: Em gửi giúp chị cái email này nha. In Hà Nội people say hộ: Anh mở cửa hộ em nhé. In Saigon, hộ sounds Northern.

Làm ơn before the verb is a more formal "please", for strangers or for a real favour. The two can go together: Làm ơn chỉ giùm tôi đường ra bến xe. Could you please show me the way to the bus station?
