There is no fixed "I" or "you". You and the other person take kinship roles based on relative age/status. Get this right and Vietnamese people visibly relax.
PHẦN I · 01
The matrix (Hanoi default)
Read the table left to right: who you're talking to, what you call THEM, and what you call YOURSELF in the same breath — the two always move together.
| Talking to... | Call them | Call yourself | Vibe |
|---|---|---|---|
| Younger person / waiter / Grab driver (younger) | em | anh (if you're male) / chị (female) | friendly-senior |
| Slightly older man (up to ~15 yrs) | anh | em | respectful-junior |
| Slightly older woman | chị | em | respectful-junior |
| Woman ~your parents' age | cô | cháu | polite-younger-gen |
| Man ~your parents' age (younger than your dad) | chú | cháu | polite-younger-gen |
| Anyone clearly older than your parents | bác | cháu | very respectful |
| Grandfather-aged man | ông | cháu | formal-respect |
| Grandmother-aged woman | bà | cháu | formal-respect |
| Small child | cháu / em | anh/chị/cô/chú | warm-senior |
| Same-age friend (casual) | cậu / bạn / ông,bà (jokey) | tớ / mình / tôi | equals |
| Stranger, formal / writing | bạn / anh/chị | tôi | neutral-safe |
| Teacher | thầy (m) / cô (f) | em | school register |

Tap whoever is standing in front of you. Every row here is copied straight from the matrix table above — the same system, read one relationship at a time instead of twelve at once.
PHẦN II · 02
The pairs, up close
The matrix above is the whole system in one table, but a handful of these pairs are worth slowing down on — they're the ones you'll actually use ten times a day.
the person younger than you
A waiter, a Grab driver younger than you, a shop assistant — call them em, and call yourself anh if you're male or chị if you're female. This is the friendly-senior pair you'll use constantly in any service interaction.
someone a bit older than you
A man up to about 15 years older is anh; a woman in the same range is chị. You call yourself em either way — this is the respectful-junior half of the same pair, just flipped.
your parents' generation
A woman around your parents' age is cô; a man in that bracket who's younger than your own father is chú. Either way, you call yourself cháu — the word Vietnamese uses for "niece/nephew/grandchild" and, by extension, "polite junior to an older adult."
clearly older than your parents
Anyone visibly older than your parents' generation is bác; a grandfather-aged man is ông; a grandmother-aged woman is bà. All three pair with cháu on your side, just at increasing levels of formality and respect.
same-age friends, the casual register
With someone genuinely your own age and a friend, the whole kinship logic relaxes: cậu, bạn, or a jokey ông/bà, paired with tớ, mình, or tôi for yourself.

Rules of thumb
- When unsure, promote them: guessing older (anh→chú) flatters mildly; guessing younger insults.
- Asking age is normal, not rude — people need it to set pronouns: "Anh bao nhiêu tuổi?"
- Third person = pronoun + ấy: anh ấy (he), chị ấy (she), cô ấy, ông ấy.
- Plurals = các / bọn / chúng: các anh (you gentlemen), bọn em (we juniors), chúng ta (we incl. you), chúng tôi (we excl. you).
- Couples: man = anh, woman = em regardless of actual age. Flirting starts the moment you pick anh/em.
- Dropping pronouns sounds either intimate or abrupt — keep them in until you can feel the difference.
- Service flattery: staff may call you
anh/chị+ call themselvesemeven if older; shops may address you assếp(boss). Play along. - The polite tag
ạstacks with everything: "Vâng ạ", "Chào bác ạ".
Guessing a bit too old costs you nothing; guessing a bit too young stings. If you're not sure where someone sits, round up.
Couples default to anh/em regardless of actual age — the man is anh, the woman is em, even if she's older. Pick anh/em with someone you're not dating and you may be saying more than you meant to.
PHẦN IV · 04
Common self-traps
| Trap | Fix |
|---|---|
Using tôi everywhere | Grammatical but cold/distant in daily Hanoi life — switch to em/anh/chị fast |
Calling a young waitress cô | She's em (or chị if older than you) — cô ages her 30 years |
Calling your landlord's mother chị | She's bà — promote! |
| One fixed word for "you" in your head | The pronoun IS the relationship; recompute per person |
| Forgetting to flip | If they're anh, you're em — the pair moves together |
PHẦN V · 05
If you remember nothing else
The pronoun IS the relationship
There is no neutral "you" — every choice sets a relationship, and you recompute it for every new person you meet.
The pair always moves together
If they're anh, you're em. If they're cô, you're cháu. You never pick your own word in isolation.
When unsure, guess older
Guessing someone is more senior than they are flatters mildly; guessing younger insults — round up.
Third person is just pronoun + ấy
anh ấy, chị ấy, cô ấy, ông ấy — take the word you'd call them to their face and add ấy for "that person."
