Vedhæftningen er for stor til at sende gennem appen.

Vedhæftningen means the attachment.

It is built from:

• vedhæftning = attachment
• -en = the definite article suffix for many Danish common-gender nouns, meaning the

So:

• en vedhæftning = an attachment
• vedhæftningen = the attachment

Danish often puts the at the end of the noun instead of using a separate word like English does.

Because vedhæftning is a common-gender noun, not a neuter noun.

In Danish, predicate adjectives often agree with the noun:

• common gender singular: stor
• neuter singular: stort
• plural / definite contexts: often store

Since vedhæftningen is common gender singular, the correct form is:

• Vedhæftningen er for stor = The attachment is too large

If the noun were neuter, you would use stort.

This is the same basic pattern as English too ... to ....

• for stor = too large
• til at sende = to send

So:

• for stor til at sende = too large to send

This is a very common Danish structure:

• for dyr til at købe = too expensive to buy
• for træt til at arbejde = too tired to work

Danish often uses the active infinitive in places where English might also use an active form, even if the meaning is a bit general.

So:

• for stor til at sende gennem appen literally looks like too large to send through the app

The understood meaning is:

• too large to be sent through the app or
• too large for sending through the app

In everyday Danish, til at sende sounds natural here. A more explicitly passive version such as til at blive sendt is possible in some contexts, but it is less natural for this sentence.

There is no explicit subject for sende in this infinitive phrase. Danish leaves it understood.

The meaning is something like:

• the attachment is too large for someone to send through the app
• the attachment is too large to send through the app

English does something similar in too large to send. The person doing the sending is understood from the situation, not stated directly.

Yes, in this sentence gennem appen means something like:

• through the app
• via the app
• using the app

Gennem literally means through, but in contexts like this it refers to the method or channel.

So the sentence means the attachment is too large to be sent using that app.

A similar alternative would be:

• via appen

That would also sound natural in many situations.

Because Danish is using the definite form: the app.

• en app = an app
• appen = the app

The sentence refers to a specific app already known from the situation, so Danish uses the definite form.

Yes. Vedhæftning is a standard word for attachment, especially in digital contexts such as email, messaging, or uploaded files.

Depending on context, Danish speakers might also talk about:

• filen = the file
• bilaget = the attachment / enclosure in some more formal contexts

But in a sentence like this, vedhæftningen is very natural.

The structure is:

• Vedhæftningen = subject
• er = verb
• for stor = predicate adjective phrase
• til at sende gennem appen = infinitive phrase explaining what it is too large for

So the full pattern is:

• [Subject] + [er] + [too + adjective] + [to + infinitive phrase]

This is very close to English structure, which makes the sentence relatively easy to understand once you know the vocabulary.

Danish would move the verb before the subject:

• Er vedhæftningen for stor til at sende gennem appen?
• Is the attachment too large to send through the app?

This is a common Danish pattern for yes/no questions: verb first, then subject.

That would be:

• En vedhæftning er for stor til at sende gennem appen.

Here the noun is indefinite:

• en vedhæftning = an attachment

Compare:

• Vedhæftningen = the attachment
• En vedhæftning = an attachment
