Elmåleren står i huset.

Because Danish, like German, commonly forms compound nouns by joining words together.

• el = electricity / electric
• måler = meter, gauge

So elmåler means electric meter or electricity meter.
Then elmåleren means the electric meter.

In Danish, the definite article is usually attached to the end of the noun instead of appearing as a separate word before it.

So:

• en elmåler = an electric meter
• elmåleren = the electric meter

The ending -en is the usual definite ending for many common-gender nouns.

Because måler is a common-gender noun in Danish, not a neuter noun.

Danish nouns have two genders:

• common gender → usually takes en in the indefinite form and -en in the definite form
• neuter → usually takes et in the indefinite form and -et in the definite form

So:

• en elmåler
• elmåleren

By contrast:

• et hus
• huset

This is a very common question for English speakers.

In Danish, when talking about where something is located, speakers often use a position verb such as:

• stå = stand
• sidde = sit
• ligge = lie

instead of just using være = be.

So Elmåleren står i huset literally uses stands, because Danish often treats objects as having a typical physical position. An electric meter is usually thought of as being upright / installed in place, so står sounds natural.

English usually just says is in the house, but Danish often prefers a more specific verb.

Not always in the strict English sense.

In Danish, stå is used quite broadly for things that are:

• upright
• fixed in place
• positioned vertically
• understood as being set somewhere in a stable position

So for many objects, står is the normal verb even if English would simply use is.

For example, Danish may use stå for things like:

• a lamp
• a bottle
• a cupboard
• a machine

The exact choice depends on how Danes typically conceptualize the object.

Because i means in or inside, and huset means the house.

So:

• i = in
• huset = the house

Together, i huset means in the house.

This tells you the meter is located inside the house, not on top of it, outside it, or attached to it in some other way.

Because hus is a neuter noun.

Its forms are:

• et hus = a house
• huset = the house

Neuter nouns usually take -et in the definite singular.
So husen would be incorrect.

The sentence follows normal Danish main-clause word order:

• Elmåleren = subject
• står = verb
• i huset = adverbial/prepositional phrase

So the pattern is:

subject + verb + place

That is very similar to ordinary English word order here.

Yes. That is grammatically correct.

Danish is a V2 language, which means the finite verb usually comes in the second position in a main clause. If you move I huset to the front for emphasis, the verb still stays second:

• Elmåleren står i huset.
• I huset står elmåleren.

The second version gives more emphasis to in the house.

A rough pronunciation guide is:

• el sounds a bit like English ell
• må contains å, which is somewhat like the vowel in British English law or more, though not exactly the same
• leren is pronounced more smoothly than an English speaker might expect, with softer Danish sounds

Very roughly, you might think of it as:

ELL-moh-leh-ren

But that is only approximate. The important point is that å is a separate Danish vowel, and it does not sound like English a in cat or name.

Yes, it is a normal practical word, especially when talking about utilities, billing, or where equipment is installed in a building.

You may also see related compounds in Danish, such as:

• vandmåler = water meter
• gasmåler = gas meter

This is another good example of how productive Danish compound nouns are.

In this sentence, the most natural interpretation is inside the house / in the building.

In other contexts, i huset can sometimes be interpreted more broadly depending on what is being discussed, but with a physical object like elmåleren, it strongly suggests actual location inside the house.
