Vietnamese family titles communicate generation, relative age, and family side — which is why the language has so many words English translates as “aunt” or “uncle.”
An imagined contemporary family reunion; kinship language depends on relationships and family usage.
Vietnamese speakers often address someone using a family term that fits their relationship, and refer to themselves with a corresponding term. Other pronouns are used too; formality and context shape the choice. Speaking to an older woman roughly your age, you become em and she becomes chị. Speaking to a child, you might be cô or chú and they become con or cháu.
These titles encode several things at once:
Generation — grandparent, parent, sibling, child
Relative age — older or younger than your parent, older or younger than you
Side of the family — mother's side or father's side
Sometimes marriage — whether someone married in
So dì (your mother's sister) and cô (traditionally your father's sister) are not interchangeable words for "aunt." They carry information that English drops.
This also extends outside the family. Strangers are addressed with the title that would fit if they were family: a young man is anh, a woman around your mother's age is cô or dì, an older man is chú or bác. It is not pretending to be related. It is a way of placing someone respectfully in relation to yourself.
Usage varies by region and by family. Southern and northern families sometimes use bác, cô, and dì differently, and plenty of families simply have their own habits. If you are unsure, listening to what your relatives call each other is the most reliable guide there is.
