This is the 157th most frequent Vietnamese word.
chúng
"Chúng" means "we," "us," or "they," depending on context.
In this sentence, 'chúng' is combined with 'tôi' to mean 'we' and is used in a context to include the speaker and others, excluding the listener.

We have completed the assignment.
'Chúng' is used here to refer to both 'us' and 'them,' representing two groups including the speaker, excluding the listener.
Chúng tôi và chúng bạn đều thích đá bóng.
We and our friends both like playing soccer.
Here, 'chúng' stands alone as a pronoun referring to 'they,' indicating a group absent of the speaker and listener.
