Tôi quen với nhà này.

A simple breakdown is:

• Tôi = I
• quen = familiar / used to / accustomed
• với = a preposition here, roughly with / to
• nhà = house / home
• này = this

So the structure is basically:

Tôi + quen với + nhà này
= I am familiar with / used to this house

Vietnamese often does not use a separate verb like English to be in sentences of this type.

In English, you say:

• I am familiar with this house.

In Vietnamese, you can simply say:

• Tôi quen với nhà này.

Here, quen works like a stative verb/adjective, so no extra am is needed.

This is very common in Vietnamese:

• Tôi mệt. = I am tired.
• Cô ấy đẹp. = She is beautiful.

Yes, very often it is.

Quen với commonly means:

• to be familiar with
• to be used to
• to become accustomed to

So it is helpful to learn quen với as a chunk, not just as two unrelated words.

Examples:

• Tôi quen với công việc này. = I’m used to this job.
• Cô ấy quen với cuộc sống ở đây. = She’s used to life here.

Here, với links quen to the thing you are familiar with or used to.

So:

• quen với + thing/situation = familiar with / used to something

For this sentence, với is important because the meaning is not just know; it is more like be familiar/accustomed to.

Compare:

• Tôi quen với nhà này.
  = I’m familiar with / used to this house.

Without với, the sentence would sound unusual for this meaning.

This is a very common question.

1. quen với

This usually means be familiar with / be used to something.

• Tôi quen với thời tiết này.
  = I’m used to this weather.

2. quen + person

With people, quen often means know / be acquainted with.

• Tôi quen anh ấy.
  = I know him. / I’m acquainted with him.

So:

• quen ai = know someone
• quen với cái gì / việc gì / nơi nào = be familiar with or used to something

That is why Tôi quen với nhà này sounds natural, but Tôi quen nhà này would normally not be the standard way to say I’m familiar with this house.

It can mean either one, depending on context.

With Tôi quen với nhà này, possible natural interpretations are:

• I’m familiar with this house
• I’m used to this house

The exact nuance depends on the situation:

• If you are talking about recognizing the place, it leans toward familiar with.
• If you are talking about adapting to living there, it leans toward used to.

Vietnamese often leaves that kind of distinction to context.

In Vietnamese, demonstratives like this and that usually come after the noun.

So:

• nhà này = this house
• người đó = that person
• xe kia = that car over there

This is different from English, where this comes before the noun.

So nhà này is the normal Vietnamese word order.

Nhà most commonly means:

• house
• home

Depending on context, it can also refer to:

• someone’s household
• family
• place of residence

In Tôi quen với nhà này, the most straightforward reading is this house/home.

If you wanted to be more specific, Vietnamese can also use:

• căn nhà này = this house
• ngôi nhà này = this house/home

But plain nhà này is completely normal in everyday speech.

Tôi is correct and neutral, but in real conversation Vietnamese often uses many other pronouns depending on age, relationship, and social situation.

For example, a speaker might say:

• em
• anh
• chị
• mình
• con

So in a textbook sentence, tôi is very common because it is clear and safe.
In real life, another pronoun may sound more natural.

Example:

• Em quen với nhà này rồi.
  = I’m used to this house already.
  (said by a younger speaker, for example)

Yes, but if you want to make that idea clearer, Vietnamese often adds words like đã or rồi.

Compare:

• Tôi quen với nhà này.
  = I’m familiar with / used to this house.

• Tôi đã quen với nhà này rồi.
  = I’ve gotten used to this house already.

So the basic sentence can express the state, while đã...rồi can make the sense of change-over-time clearer.

Usually, for this meaning, no.

If you want to say I’m familiar with this house or I’m used to this house, the normal form is:

• Tôi quen với nhà này.

Without với, quen is much more natural with people:

• Tôi quen anh ấy. = I know him.

So learners should be careful not to drop với when talking about familiarity with things, places, or situations.

It is natural, but native speakers might choose slightly different versions depending on context.

Possible versions:

• Tôi quen với nhà này.
  Neutral and correct.

• Tôi quen với căn nhà này.
  Slightly more specific: this house/building.

• Tôi đã quen với nhà này rồi.
  More clearly: I’ve gotten used to this house.

• Tôi rất quen với ngôi nhà này.
  I’m very familiar with this house.

So your sentence is fine, but Vietnamese offers several natural variants.

A learner-friendly pronunciation guide is roughly:

• Tôi ≈ toy
• quen ≈ somewhat like kwehn
• với ≈ roughly vuhy or wuhy, with a rising-glottal tone depending on dialect
• nhà ≈ nyaa
• này ≈ nai with a rising tone

A few points:

• nh in nhà sounds like the ny in canyon.
• qu in quen is pronounced more like kw.
• Tones matter a lot, especially in với, nhà, and này.

If you are studying pronunciation, it is best to learn the sentence with audio, because tones are hard to capture well in English spelling.

It is often easiest to think of quen as a stative word that can behave a bit like either an adjective or a verb, depending on how your textbook explains Vietnamese grammar.

For English speakers, the important practical point is:

• You can use quen directly as the main predicate.
• You do not need a separate word for to be.

So whether a grammar book labels it an adjective or stative verb, the sentence pattern stays the same:

• Tôi quen với nhà này.

That is the part you should remember first.
