Znám hodnotu domu.

In Czech, znát and vědět both relate to knowing, but they are used differently.

• znát = to know someone/something, to be familiar with
• vědět = to know a fact, to know that..., to be aware of information

In Znám hodnotu domu, the object is a noun phrase: hodnotu domu = the value of the house. Czech normally uses znát with this kind of direct object.

So:

• Znám hodnotu domu. = I know the value of the house.

If you wanted to use vědět, you would usually rephrase the sentence as a fact or clause, for example:

• Vím, jakou má dům hodnotu. = I know what value the house has.

So the sentence you were given is the natural straightforward version.

Znám is the 1st person singular present tense form of znát.

So it means:

• znám = I know

The full subject já is not needed, because the verb ending already shows who the subject is.

Compare:

• znám = I know
• znáš = you know
• zná = he/she/it knows

Czech often leaves out subject pronouns when they are already clear from the verb form.

So:

• Znám hodnotu domu. already clearly means I know the value of the house

You could say:

• Já znám hodnotu domu.

but that usually adds emphasis, something like:

• I know the value of the house

In normal neutral speech, dropping já is more natural.

Because it is the direct object of the verb.

The basic dictionary form is:

• hodnota = value

But in this sentence, value is the thing being known, so Czech uses the accusative case.

For a feminine noun like hodnota, the accusative singular is:

• hodnotu

So:

• znám hodnotu = I know the value

This is a very common pattern in Czech: the direct object changes form according to case.

Here domu is the genitive singular of dům.

• dům = house
• domu = of the house

Czech often expresses noun + of + noun using the genitive case.

So:

• hodnota domu = the value of the house

This is one of the most important uses of the genitive in Czech.

A useful way to think about it:

• hodnota = value
• domu = of the house

Together: value of the house

Yes.

More literally, the structure is:

• hodnotu = value (accusative, because it is the object)
• domu = of the house (genitive)

So the phrase means:

• the value of the house
• or more naturally in English, sometimes the house's value

Czech often uses case endings where English uses words like of.

Czech does not have articles like a or the.

So a noun like dům can mean:

• a house
• the house

and the exact meaning depends on context.

The same is true for hodnota / hodnotu:

• value
• the value

So Znám hodnotu domu can naturally mean:

• I know the value of the house

even though there is no separate word for the.

No, Czech word order is more flexible than English word order because the case endings show the grammatical roles.

Znám hodnotu domu. is a neutral, natural order.

But you could also say:

• Hodnotu domu znám.

This still means the same thing, but it gives more emphasis to hodnotu domu.

Very roughly:

• Znám hodnotu domu. = neutral statement
• Hodnotu domu znám. = The value of the house, I know it

So the original sentence is probably the best basic version for a learner, but other orders are possible.

A simple pronunciation guide:

• Znám ≈ znaam
• hodnotu ≈ HOD-no-too
• domu ≈ DO-moo

A few important points:

• Czech stress is usually on the first syllable of each word.
• á in znám is a long vowel.
• Zn- at the start of znám may feel awkward for English speakers, because English rarely begins words with that cluster.

A rough overall pronunciation:

• ZNAAM HOD-no-too DO-moo

Yes, and this is a very common point of confusion.

These are different forms:

• domu = of the house / to the house in some contexts, depending on case/function
• domů = homeward, to home, going home

In your sentence, it is definitely:

• hodnotu domu = the value of the house

because the phrase requires the genitive of the house.

The difference in writing matters:

• domu = no accent on the final u
• domů = long ů

So do not confuse:

• hodnota domu = value of the house with
• jdu domů = I am going home

Not exactly, though the meanings can overlap in some contexts.

• hodnota = value
• cena = price

So:

• Znám hodnotu domu. = I know the value of the house.
• Znám cenu domu. = I know the price of the house.

Value may suggest worth, market value, or estimated value. Price is more specifically the amount asked or paid.

So if the Czech sentence uses hodnotu, value is the better translation.
