Together: cùng (với)

Cùng means "together": people do something at the same time, as one group. When the people come first, put cùng before the verb: Mình cùng đi nha. Let's go together. With nobody named, the everyday way to say "together" is cùng nhau or với nhau: Mình cùng nhau học nha. Let's study together.

To name the person you do it with, put cùng or cùng với after the verb, then the person: Chị có muốn đi cùng tụi em không? Do you want to come with us? In everyday speech với alone is often enough: Em đi chợ với mẹ. I'm going to the market with Mum. Cùng makes the "together" clearer, and you'll see it a lot in invitations and writing. In Saigon you'll also hear chung in the same place: đi chung, go together.

Before a noun, cùng means "the same": cùng tuổi (the same age), học cùng lớp (in the same class).

Cùng, with the falling tone, is easy to confuse with cũng, which means "also". Em cũng đi means "I'm going too"; Mình cùng đi means "we go together". They can meet in one sentence: Em cũng đi cùng. I'm coming along too.
