English trap
Do not put không at the end of a statement unless it is part of a question pattern.
Right vs wrong examples
| Instead of this | Say this | Why |
|---|---|---|
| Copy the English structure word by word | Tôi không hiểu | Use the Vietnamese pattern as a ready-made chunk. |
| Add extra grammar words because English needs them | Tôi không ăn thịt | Vietnamese often stays shorter than English. |
| Study the rule without a real situation | Không cay | Attach the rule to a cafe, taxi, hotel, market, or work sentence. |
Core examples
| Vietnamese | English | Practice note |
|---|---|---|
| Tôi không hiểu | I do not understand | Không goes before the verb. |
| Tôi không ăn thịt | I do not eat meat | Keep the action after không. |
| Không cay | Not spicy | Short request at food stalls. |
| Không đường | No sugar | Useful drink request. |

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 |
|---|---|---|
| Tôi không hiểu | change the person or topic | Tôi không ăn thịt |
| Tôi không ăn thịt | change the time, place, or object | Không cay |
| Không cay | say it as a real request or answer | Không đường |
Real situation
Use this beginner foundation 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.
