Vent et sekund.

Because vent is the imperative form of the verb at vente (to wait).

• at vente = infinitive
• venter = present tense, wait / am waiting / is waiting
• vent = command, wait!

So Vent et sekund. uses the form you use when telling someone to do something.

In Danish, just like in English, the subject is usually left out in commands.

• Vent et sekund. = Wait a second.
• You do not normally say Du vent et sekund.

The person you are speaking to is understood automatically.

Because sekund is a neuter noun in Danish, so it takes et in the indefinite singular.

Danish nouns are mainly divided into two grammatical genders:

• en-words
• et-words

Since sekund is an et-word, you say:

• et sekund = a second

If it were a common-gender noun, it would take en instead.

Basically yes. Sekund means the time unit second.

In this sentence, though, it is also being used in a more everyday way, like English a second in:

• Wait a second.

So it does not always have to sound mathematically exact; it can simply mean a moment.

It is natural and common, but it can sound a little direct depending on tone and situation.

It is fine in many everyday contexts, especially with friends, family, coworkers, or when speaking quickly. But if you want to sound softer or more polite, Danish often adds a small softening word such as lige:

• Vent lige et sekund. = Just wait a second.

Other softer alternatives include:

• Vent lidt. = Wait a bit.
• Et øjeblik. = One moment.
• Kan du vente et sekund? = Can you wait a second?

Here et is the indefinite article, meaning a / an.

So:

• et sekund = a second

It is not the pronoun it, even though et can also appear in other grammatical roles elsewhere in Danish. In this sentence, it is simply the article that matches the noun sekund.

Yes, and that is extremely common.

Lige often softens a command and makes it sound more natural and less abrupt. It does not literally mean exactly here. In this kind of sentence, it often works more like just in English.

So:

• Vent et sekund. = more direct
• Vent lige et sekund. = softer, more conversational

A rough learner-friendly guide would be something like:

• Vent: sounds a bit like vent in English, but with a Danish vowel quality
• et: often reduced and said very quickly
• sekund: stress is on the second syllable: se-KUND

A few useful pronunciation notes:

• The t in et may be very weak in fast speech.
• In connected speech, vent et can run together quite a bit.
• The final d in sekund is not pronounced like a strong English d.

So in natural speech, the whole sentence may sound smoother and less clearly separated than the spelling suggests.

Yes. Et øjeblik means a moment and is also very common.

Compare:

• Vent et sekund. = Wait a second.
• Vent et øjeblik. = Wait a moment.

Both are natural. Et øjeblik can sound a little more neutral or slightly more polite in some situations, while et sekund is very common in casual speech.

No. Danish does not have a separate polite you form in normal modern usage, and the imperative form does not change for singular vs. plural.

So vent can be used whether you are speaking to:

• one person
• several people
• someone you know well
• someone more formally

Politeness is usually shown through tone, wording, and softeners like lige, not through a different verb form.

Vent et sekund is the normal and straightforward word order for a command:

1. imperative verb: Vent
2. object/time expression: et sekund

You can expand it, but the basic order stays the same:

• Vent lige et sekund.
• Vent et lille sekund.
• Vent bare et sekund.

For a simple command, starting with the verb is standard.
