Fastprisaftalen er en elaftale.

Because Danish, like German, very often forms nouns by making compound words.

Here, Fastprisaftalen is built from:

• fastpris = fixed price
• aftale = agreement / contract
• -n / -en = the definite ending

So the underlying noun is fastprisaftale = a fixed-price agreement, and fastprisaftalen = the fixed-price agreement.

The same thing happens in elaftale:

• el = electricity
• aftale = agreement / contract

So elaftale means an electricity agreement / electricity contract.

It marks the noun as definite singular: the.

So:

• en fastprisaftale = a fixed-price agreement
• fastprisaftalen = the fixed-price agreement

This is a major difference from English. In Danish, the is often added to the end of the noun instead of appearing as a separate word.

Because in Danish, the definite article is usually attached to the noun as a suffix.

So English:

• the agreement

often becomes Danish:

• aftalen

not the + agreement as two separate words.

That is why the sentence starts with Fastprisaftalen, not something like den fastprisaftale.

A separate word such as den is usually used when there is an adjective in front:

• den store aftale = the big agreement

But with just the noun by itself, Danish normally uses the ending:

• aftalen = the agreement

Because aftale is an en-word in Danish, not an et-word.

So:

• en aftale
• en fastprisaftale
• en elaftale

In Danish compounds, the last part of the compound usually determines the grammatical gender. Since the last part is aftale, the whole word takes en.

Er is the present tense of at være = to be.

So:

• jeg er = I am
• du er = you are
• han/hun er = he/she is
• det er = it is
• de er = they are

In this sentence, er simply means is:

• Fastprisaftalen er en elaftale. = The fixed-price agreement is an electricity contract.

In Danish, nouns are not normally capitalized the way they are in German.

The only reason Fastprisaftalen has a capital letter here is that it is the first word of the sentence.

If the same word appeared in the middle of a sentence, it would normally be lowercase:

• Jeg læste fastprisaftalen i går. = I read the fixed-price agreement yesterday.

So this capitalization is just normal sentence-start capitalization.

The word order is very straightforward:

• Fastprisaftalen = subject
• er = verb
• en elaftale = subject complement

So it follows the same basic pattern as English:

• X is Y

In other words:

• Fastprisaftalen = what we are talking about
• er = links the two parts
• en elaftale = what it is

You would usually put the verb first:

• Er fastprisaftalen en elaftale?

That is a very common Danish pattern for yes/no questions.

Compare:

• Fastprisaftalen er en elaftale. = statement
• Er fastprisaftalen en elaftale? = question

So Danish often forms questions by inverting subject and verb, much like English does in some structures.

You add ikke = not:

• Fastprisaftalen er ikke en elaftale.

So:

• er = is
• er ikke = is not

This is the normal way to negate a sentence like this.

El means electricity or electrical power.

It is very common in Danish compounds, for example:

• elbil = electric car
• elpris = electricity price
• elselskab = electricity company
• elaftale = electricity agreement / electricity contract

So elaftale is literally an electricity agreement.

Not always exactly, but it often overlaps.

Aftale can mean:

• agreement
• arrangement
• deal
• contract

In business or utility contexts, aftale is often very naturally translated as contract or agreement.

So in this sentence, elaftale can be understood as an electricity agreement or electricity contract, depending on the context.

A simple learner-friendly approximation would be:

• Fastprisaftalen: FAST-pris-af-ta-lehn
• er: a short air / er sound
• en: a very weak en
• elaftale: EL-af-ta-le

A few useful notes:

• Danish r is not usually pronounced like a strong English r.
• Unstressed endings such as -e and -en are often pronounced quite weakly.
• In compounds, the first part often gets clear stress, so FASTpris... and ELaftale are easier to hear in chunks.

If you want to sound natural, it helps to learn the sentence as rhythm groups rather than letter by letter:

• Fastprisaftalen / er en elaftale
