English trap
Do not move every question word to the front like English.
Right vs wrong examples

|---|---|---|
| Copy the English structure word by word | Cái này là gì? | Use the Vietnamese pattern as a ready-made chunk. |
| Add extra grammar words because English needs them | Bạn đi đâu? | Vietnamese often stays shorter than English. |
| Study the rule without a real situation | Khi nào đi? | 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 |
|---|---|---|
| Cái này là gì? | change the person or topic | Bạn đi đâu? |
| Bạn đi đâu? | change the time, place, or object | Khi nào đi? |
| Khi nào đi? | say it as a real request or answer | Mấy giờ gặp? |
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 often prefers practical, context-rich examples. Learn the pattern through a line you might actually say.

- Replace one noun or time word.
- Listen to the slow audio, then say the new sentence twice.
