Người đó đang đợi ở trước công ty.

A natural breakdown is:

• người = person
• đó = that / that one
• đang = currently, in the middle of
• đợi = wait
• ở trước = in front of
• công ty = company

So the structure is roughly:

người đó + đang đợi + ở trước công ty
= that person + is waiting + in front of the company

In Vietnamese, demonstratives like này, kia, and đó usually come after the noun.

So:

• người đó = that person
• công ty này = this company
• cuốn sách kia = that book over there

This is normal Vietnamese word order. English says that person, but Vietnamese says person that.

It can, depending on context.

Người đó literally means that person, so it is more neutral than English he or she. Vietnamese often avoids gendered pronouns unless the relationship, age, or social role is important.

So if the meaning in context is clear, người đó may be translated as:

• that person
• he
• she
• sometimes even they in very general English translation

If you specifically wanted he or she, Vietnamese might use something like:

• anh ấy = he
• cô ấy = she
• ông ấy = he, older man
• bà ấy = she, older woman

Đang marks an action as in progress.

So:

• đợi = wait / to wait
• đang đợi = be waiting / currently waiting

It works a lot like the English be + -ing form, although it is not exactly identical in every situation.

In this sentence, đang tells you the person is in the middle of waiting right now.

Yes, often you can.

• Người đó đợi ở trước công ty.
• Người đó đang đợi ở trước công ty.

Both can be understood, but đang makes the ongoing action more explicit.

Very roughly:

• đợi = waits / is waiting / wait, depending on context
• đang đợi = is waiting right now

Vietnamese often relies on context, so aspect markers like đang are helpful but not always required.

They are very close in meaning. Both mean to wait.

Examples:

• đợi xe buýt = wait for the bus
• chờ xe buýt = wait for the bus

In many everyday situations, they are interchangeable. Learners will hear both a lot.

There can be small differences in style, region, or habit, but at a basic level you can treat them as near-synonyms.

Yes, trước công ty is also possible in many contexts.

• ở is a location marker, roughly like at/in
• trước means in front of here

So:

• ở trước công ty = at the front of the company / in front of the company
• trước công ty = in front of the company

Including ở can make the location feel a little more explicit. In natural speech, Vietnamese often allows either form depending on style and rhythm.

No. Trước can refer to either:

1. space: in front of
2. time: before

Examples:

• đứng trước nhà = stand in front of the house
• trước 8 giờ = before 8 o’clock

In ở trước công ty, it clearly means in front of because it is being used as a location phrase.

Vietnamese does not use articles like English a, an, and the.

So công ty can mean:

• a company
• the company
• sometimes just company

The exact meaning depends on context.

In this sentence, English would usually translate it as the company if both speaker and listener already know which company is meant.

The sentence follows a very common Vietnamese pattern:

Subject + aspect marker + verb + location

Here that is:

• Người đó = subject
• đang = aspect marker
• đợi = verb
• ở trước công ty = location

So the full pattern is:

Người đó / đang / đợi / ở trước công ty

Vietnamese word order is often quite straightforward, and location phrases commonly come after the verb.

A rough tone guide:

• Người = falling-glottal tone on ười
• đó = rising tone
• đang = level tone
• đợi = heavy/low broken tone
• ở = falling-glottal tone
• trước = rising tone
• công = level tone
• ty = level tone

A rough English-style approximation is not perfect, but something like:

ngwuh-ee doh dang duh-ee uh tru-uhk kong tee

A few important notes:

• đ is a separate letter in Vietnamese and sounds like English d
• ng at the start of người is normal in Vietnamese, even though it feels unusual for English speakers
• tones matter, so try to learn each word together with its tone, not just its consonants and vowels
