Měřidlo je v domě; rozúčtování a zúčtovací období jsou v podkladech.

Because the subject changes from singular to plural.

• Měřidlo je v domě.
  • měřidlo = one thing, so Czech uses je = is
• Rozúčtování a zúčtovací období jsou v podkladech.
  • there are two items joined by a (and), so Czech uses jsou = are

So this is just normal subject-verb agreement:

• singular → je
• plural → jsou

Because they come after the preposition v, which here expresses location (in), so Czech uses the locative case.

Examples from the sentence:

• dům → v domě = in the house/building
• podklady → v podkladech = in the documents/materials

So the sentence is a good example of how Czech nouns change form depending on their grammatical role.

The basic form is dům (house / building), but after v for location, it changes to the locative singular form domě.

So:

• dům = dictionary form
• v domě = in the house/building

This is something English speakers often need to get used to: in Czech, prepositions often require a specific case, so the noun changes form.

For the same reason: v with a location meaning requires the locative.

Here the noun is plural:

• podklady = basic plural form
• v podkladech = locative plural

So:

• podklady = documents / supporting materials
• v podkladech = in the documents / in the supporting materials

Because Czech does not have articles like English a / an / the.

So a phrase like v domě can mean:

• in a house
• in the house
• in the building

The exact meaning depends on context.

That is very normal in Czech. Learners often want to insert an article mentally, but Czech simply does not work that way.

Měřidlo is a general word for a measuring device or meter.

Depending on context, it could refer to something like:

• a utility meter
• a measuring instrument
• a gauge

In technical or housing-related language, měřidlo often means some kind of installed meter. It is a bit more formal or technical than an everyday English meter.

A learner may also meet měřič, which can sometimes overlap in meaning, but měřidlo sounds more like the device/instrument itself.

It is a noun.

It comes from the verb rozúčtovat / rozúčtování and refers to the allocation or distribution of charges/costs.

So grammatically, it behaves like a thing or concept, not an action word in this sentence.

In administrative or housing contexts, rozúčtování often means something like:

• cost allocation
• bill breakdown
• distribution of charges among tenants/units

This is a noun phrase made of:

• zúčtovací = an adjective
• období = a noun meaning period

Together, it means billing period, settlement period, or accounting period, depending on context.

Grammatically:

• období is the main noun
• zúčtovací describes it

So it works like English billing period.

Because v domě and doma are not the same thing.

• v domě = in the building / in the house
• doma = at home

Doma is about being at one’s home base, not specifically about being physically inside a building in a neutral, technical sense.

This sentence sounds administrative/technical, so v domě is the natural choice.

No. In this context, podklady usually means supporting documents, materials, or documentation.

So v podkladech means something like:

• in the documents
• in the supporting materials
• in the paperwork

Even though the literal root may suggest something like a base or underlying material, in real usage it often refers to documents used as the basis for a decision, report, or calculation.

Yes. The semicolon is natural, especially in a more formal or administrative style.

It separates two closely related statements:

• Měřidlo je v domě
• rozúčtování a zúčtovací období jsou v podkladech

A semicolon is stronger than a comma and helps show that these are two linked pieces of information.

You could also see this written as two separate sentences in some contexts.

Czech word order is fairly flexible, but this sentence uses a neutral, straightforward order.

Current order:

• Měřidlo je v domě; rozúčtování a zúčtovací období jsou v podkladech.

This sounds natural and informational.

Czech can move words around for emphasis, but that would usually change the focus rather than the core meaning. For a learner, the given word order is a good standard model.

A rough guide:

• měřidlo: the beginning mě sounds roughly like mye
• ř is the famous Czech sound that does not exist in English; it is somewhat like a mix of r and zh
• zúčtovací: the long vowel ú is held longer, and č sounds like ch in church

Very rough approximations:

• měřidlo ≈ mye-rzhid-lo
• zúčtovací ≈ zooch-toh-va-tsee

These are only approximations, but they can help an English speaker get started.
