Elektroměr je vedle dveří.

Elektroměr means electricity meter or electric meter.

It is made from:

• elektro- = electricity / electrical
• -měr = meter, measuring device

So it is literally a device that measures electricity usage.

Je means is. It is the 3rd person singular form of být (to be).

So:

• Elektroměr je vedle dveří.
• The electricity meter is next to the door.

In Czech, the verb to be is normally stated in sentences like this, unlike in some other languages where it may be omitted.

Because vedle normally requires the genitive case when it means next to / beside.

So dveře changes to dveří.

• nominative: dveře = door / doors
• genitive: dveří

That is why the sentence says:

• vedle dveří = next to the door

In Czech, dveře is one of those nouns that is grammatically plural in form even when it refers to a single object in English: a door.

This is similar to words like:

• kalhoty = trousers
• nůžky = scissors

So although English says the door, Czech uses the plural-looking noun dveře. After vedle, it becomes dveří.

Formally, dveří is a genitive plural form, because dveře is treated as a plural noun.

So even when you translate it as of the door or next to the door, the Czech grammar still uses a plural form.

That is normal and not something you need to force into English logic too much. The important pattern is:

• dveře
• vedle dveří

No. Czech does not use articles like a, an, or the.

So:

• Elektroměr can mean an electricity meter or the electricity meter
• dveří can mean of a door or of the door

The exact meaning depends on context. In this sentence, English naturally uses the:

• The electricity meter is next to the door.

Yes, Czech word order is fairly flexible.

The neutral order here is:

• Elektroměr je vedle dveří.

But other word orders are possible, for example:

• Vedle dveří je elektroměr.

This still means the same thing, but the focus is a little different.
The second version emphasizes the location first: Next to the door, there is an electricity meter.

So Czech uses word order partly for emphasis and information structure, not only for basic grammar.

Not in a normal full sentence with this meaning.

• Elektroměr je vedle dveří. = complete sentence
• Elektroměr vedle dveří = more like a fragment, note, or label

If you want to say The electricity meter is next to the door, you should keep je.

A rough pronunciation guide is:

eh-LEK-tro-myer yeh VED-leh DVEH-zhee

A few notes:

• ě often makes the preceding consonant sound softer; in měr, it sounds roughly like myer
• ř in dveří is the famous Czech sound, difficult for English speakers; it is something like a rolled or buzzing rzh
• stress in Czech usually falls on the first syllable of each word:
  • ELEKtroměr
  • je
  • VEDle
  • DVEří

Vedle usually means next to, beside, or alongside.

In this sentence:

• vedle dveří = next to the door

It is a very common preposition for physical location.

However, exact English translation can vary by context:

• sedí vedle mě = he/she is sitting next to me
• vedle domu = next to the house

The key grammar point is that vedle is followed by the genitive here.

Sometimes, but the meaning changes.

For example:

• u dveří = by the door / at the door
• před dveřmi = in front of the door
• za dveřmi = behind the door
• vedle dveří = next to the door

So vedle is specifically about being at the side of something.

Elektroměr is in the nominative case, because it is the subject of the sentence.

Structure:

• Elektroměr = subject, nominative
• je = verb
• vedle dveří = prepositional phrase, with dveří in the genitive

So this is a very standard Czech sentence pattern:

• subject + být + location

Yes. Elektroměr je vedle dveří. is a completely natural, correct Czech sentence.

It is simple, clear, and useful for describing location. It is a good example of:

• basic word order
• the verb být
• a location expression
• a preposition that takes the genitive case
