Questions & Answers about Lan đang ho.
Is Lan a person’s name?
Yes. Lan is a Vietnamese given name, and it is very commonly a woman’s name. In this sentence, Lan is simply the subject: the person who is coughing.
What does đang do in this sentence?
Đang marks an action as being in progress. It is often similar to the English be + -ing form.
So in Lan đang ho, đang shows that the coughing is happening now or around now, not just as a general fact.
A useful pattern is:
subject + đang + verb
For example:
- Lan đang học. = Lan is studying.
- Tôi đang ăn. = I am eating.
Why is there no separate word for is?
Vietnamese does not build the progressive the same way English does.
In English, you say is coughing:
- is = auxiliary verb
- coughing = main verb
In Vietnamese, you do not need a separate equivalent of English is here. Instead, Vietnamese uses:
- the subject: Lan
- an aspect marker: đang
- the verb: ho
So the structure is more like:
Lan + ongoing-action marker + cough
That is completely normal Vietnamese grammar.
