Vietnamese is a bit different than Romance languages, in that Vietnamese doesn't just use different pronouns for casual or formal situations, but Vietnamese actually uses different pronouns depending on the relation between the speaker and his/her audience. This relation takes gender, age, and status into account. Basically, Vietnamese refer to everyone as a family member. Also, it is common to use a third person personal pronoun in the first person.

Singular pronouns [ edit ]

bạn (friend) informal, but not casual; a general-purpose version; use with caution anh (brother) to a male who is the same age as the speaker bà (grandmother, old lady) formal; to a female who is older than the speaker chị (sister) informal; to a female who is the same age as or older than the speaker con (child) from an adult to a child em(younger sister or brother) to a female who is the same age as the speaker, or to a person (of either gender) who is younger than the speaker (such as a child) mày (you) informal, even rude or insulting; to a person younger than the speaker, or to a person held in low esteem; use with caution ông (grandfather, old man) formal; to a male who is older than the speaker cô (father's sister) formal; to an older woman as old as one's father, a young (usually unmarried) woman

In addition, there are different pronouns for each kind of relative. For a listing of those pronouns, see Family.
