One form, always
ăn (eat) is always ăn. I eat, she ate, they will eat — the verb never changes. The person and the time come from other words in the sentence.
| Vietnamese | Literal | English |
|---|---|---|
| Tôi ăn | I eat | I eat / ate / am eating — context decides |
| Anh ấy ăn | he eats | He eats / ate |
| Họ ăn | they eat | They eat / ate |
| Hôm qua tôi ăn phở | yesterday I eat phở | I ate phở yesterday |
Time words like hôm qua (yesterday) do the work English puts on the verb.
The three core markers: đã, đang, sẽ
| Marker | Rough role | Example |
|---|---|---|
| đã | completed / already | Tôi đã ăn — I've eaten / I ate |
| đang | in progress right now | Tôi đang ăn — I'm eating |
| sẽ | future / intention | Tôi sẽ ăn — I'll eat |
| vừa mới | just did | Tôi vừa mới đến — I just arrived |
| chưa | not yet | Tôi chưa ăn — I haven't eaten yet |
| đã từng | have ever done | Tôi đã từng đến Việt Nam — I've been to Vietnam before |
Tôi đã ăn
I ate / I've eaten
Tôi đang ăn
I'm eating (right now)
Tôi sẽ ăn
I'll eat
Tôi vừa mới đến
I just arrived
Tôi chưa ăn
I haven't eaten yet
Time anchors — the easy way
Drop a time word in and the sentence sorts itself out. These are the highest-frequency anchors:
| Vietnamese | English |
|---|---|
| hôm qua | yesterday |
| hôm nay | today |
| ngày mai | tomorrow |
| ngày kia | the day after tomorrow (S: ngày mốt) |
| bây giờ | now |
| tuần này | this week |
| tuần sau | next week |
| tuần trước | last week |
| tháng này | this month |
| tháng sau | next month |
Ngày mai tôi đi Hà Nội
Tomorrow I'm going to Hanoi
No marker needed — ngày mai already says 'future'.
Hôm qua tôi ăn phở
Yesterday I ate phở
Bây giờ tôi đang học
I'm studying now
Tuần sau tôi sẽ về
Next week I'll go back
Why context matters more than markers
English grammar forces every verb to declare its tense. Vietnamese doesn't — and that's a feature, not a gap. The marker appears when the speaker wants to emphasize completion, progress, or intention:
- Tôi ăn rồi — 'I ate already' (rồi marks it as done, very common colloquially).
- Tôi đã ăn — the same completion, a bit more explicit.
- Hôm qua tôi ăn phở — time word alone; nobody asks 'ate or eat?'.
Summary
Verbs never change; đã/đang/sẽ mark completed, in-progress, future when time words or context don't already make it clear; time anchors like hôm qua and ngày mai do most of the daily work. Next: questions and negation — how to say no and ask anything.
