The short version

Pattern box
trước khi/sau khi/khi + action: Sau khi ăn, tôi đi.
English trap
Do not make a long English clause; start with two short actions.
Right vs wrong examples
| Instead of this | Say this | Why |
|---|---|---|
| Copy the English structure word by word | Trước khi ăn, rửa tay | Use the Vietnamese pattern as a ready-made chunk. |
| Add extra grammar words because English needs them | Sau khi ăn, uống thuốc | Vietnamese often stays shorter than English. |
| Study the rule without a real situation | Khi đến, gọi tôi | Attach the rule to a cafe, taxi, hotel, market, or work sentence. |

How to use it in real sentences
Use the examples as sentence patterns, not isolated vocabulary. Say the whole line first, then replace one small part such as the person, time, object, or place.
Substitution drill
| Base sentence | Change this | New sentence |
|---|---|---|
| Trước khi ăn, rửa tay | change the person or topic | Sau khi ăn, uống thuốc |
| Sau khi ăn, uống thuốc | change the time, place, or object | Khi đến, gọi tôi |
| Khi đến, gọi tôi | say it as a real request or answer | Trước khi đi, tôi uống cà phê |
Real situation
Use this sentence building grammar when a real conversation forces you to speak quickly. Pick one sentence from the examples, imagine the situation, then change only one detail so the grammar becomes usable instead of abstract.
Southern Vietnamese note
Southern Vietnamese often prefers practical, context-rich examples. Learn the pattern through a line you might actually say.
Practice drill
- Read each Vietnamese sentence aloud.
- Replace one noun or time word.
- Listen to the slow audio, then say the new sentence twice.
- Cover the English and recall the Vietnamese from the situation.
- Save the examples you would actually use this week.
