Vänta en sekund.

Because this is an imperative sentence, used for commands or requests. In Swedish, imperatives usually do not include the subject pronoun.

So instead of saying Du vänta en sekund, Swedish simply says:

Vänta en sekund.

This is like English Wait a second., where you is also usually left out.

Vänta is the imperative form of the verb att vänta = to wait.

A few useful forms are:

• att vänta = to wait
• jag väntar = I wait / I am waiting
• vänta! = wait!

For many Swedish verbs ending in -a in the infinitive, the imperative looks the same as the basic verb stem, so vänta stays vänta.

Because sekund is an en-word in Swedish.

Swedish nouns have two grammatical genders:

• en-words
• ett-words

Since sekund belongs to the en group, you say:

• en sekund

not:

• ett sekund

This is something learners usually have to memorize with each noun.

It can, but in this sentence en functions like the English article a/an.

So:

• en sekund = a second

Depending on context, en can also mean one, but here the natural interpretation is simply a.

Because vänta and vänta på are used differently.

• vänta en sekund = wait a second / wait for a moment
• vänta på någon/något = wait for someone/something

Examples:

• Vänta en minut. = Wait a minute.
• Jag väntar på bussen. = I’m waiting for the bus.

So in Vänta en sekund, en sekund expresses a length of time, not the thing you are waiting for.

It depends mostly on tone of voice and context.

By itself, Vänta en sekund is very common and often perfectly normal, especially in everyday speech. It can sound like:

• Wait a second
• Just a moment

If you want to sound softer or more polite, you could say:

• Vänta lite. = Wait a little.
• En sekund, tack. = One second, please.
• Vänta lite, snälla. = Wait a bit, please.

So the phrase itself is not automatically rude.

A rough pronunciation guide is:

VEN-ta

A few points:

• ä sounds somewhat like the vowel in English bed, though not exactly the same.
• The v is pronounced like an English v.
• The nt is pronounced clearly.
• The stress is on the first syllable: VÄN-ta

If you already know IPA, it is approximately [ˈvɛnːta] in many pronunciations.

Not really, although they are related in meaning.

sekund is roughly pronounced:

seh-KUND

Key points:

• stress is on the second syllable
• the u is not the same as English uh
• the final d is pronounced

Approximate IPA: [sɛˈkɵnd] in standard Swedish.

So it does not sound like English second, even though it means the same thing.

Because Swedish imperative sentences normally start with the verb.

So:

• Vänta en sekund. = Wait a second.

This is normal for commands. In a regular statement, Swedish often has the subject before the verb, for example:

• Du väntar. = You are waiting.

But in commands, the verb comes first and the subject is usually omitted.

Yes. Swedish often uses several similar expressions.

Common alternatives include:

• Vänta lite. = Wait a bit.
• Vänta en minut. = Wait a minute.
• Ett ögonblick. = One moment.
• En sekund. = One second. / Just a second.

These all work in everyday speech, though the tone may differ slightly. Vänta en sekund is very natural and common.

Yes, sekund is singular here.

Its forms are:

• en sekund = a second
• sekunden = the second
• sekunder = seconds
• sekunderna = the seconds

So if you wanted to say Wait two seconds, you would say:

Vänta två sekunder.
