Wacht nog een seconde.

Wacht is the imperative form of the verb wachten (to wait).

• wachten = infinitive, the dictionary form
• wacht! = command to one person, like wait!

So Wacht nog een seconde. means Wait another second.

For commands in Dutch, you usually use the bare verb stem:

• lopen → Loop!
• komen → Kom!
• wachten → Wacht!

By itself, Wacht is usually an imperative directed at one person, often in an informal way.

If you want to be more explicit or formal, Dutch can also use:

• Wacht! = wait! (usually to one person)
• Wacht even! = wait a moment!
• Wacht u even. = please wait a moment (formal/polite)
• Wachten jullie even. = wait a moment, you all

In everyday speech, Wacht nog een seconde sounds natural when speaking casually to one person.

Here nog means something like another, a bit longer, or still depending on how you translate it.

In Wacht nog een seconde, it gives the idea of:

• wait one more second
• wait another second
• wait just a second longer

This is a very common use of nog in Dutch. It often adds the idea of continuation or addition.

Compare:

• Wacht een seconde. = Wait a second.
• Wacht nog een seconde. = Wait another second / Wait one more second.

Both are possible, but they are slightly different.

• Wacht een seconde. = Wait a second.
• Wacht nog een seconde. = Wait another second / Wait a little longer.

So nog adds the idea that the waiting should continue a bit more. Without nog, the sentence is more neutral.

Good question. In Dutch, een usually means a/an.

• een seconde = a second

If you want to stress the number one, Dutch often writes één with an accent:

• één seconde = one second, specifically one

In your sentence, een seconde just means a second. There is no special emphasis on the number.

Yes, in this sentence seconde means the unit of time: second.

It is a common noun:

• een seconde = a second
• twee seconden = two seconds

Dutch also often uses moment in similar situations:

• Wacht een moment. = Wait a moment.
• Wacht even. = Wait a moment / Hang on.

Because this is a command. In Dutch imperatives, the subject is usually left out, just like in English:

• Wait!
• Wacht!

You can add a subject sometimes for emphasis or contrast, but normally you do not.

For example:

• Jij wacht hier. = You wait here.
  This is more emphatic and not the normal simple imperative.

So Wacht nog een seconde. is the standard natural command form.

The order is:

verb + adverb + object

• Wacht = verb
• nog = adverb
• een seconde = time expression / object-like phrase

This is normal for short imperative sentences in Dutch.

A similar pattern:

• Kom straks terug. = Come back later.
• Blijf nog even hier. = Stay here a little longer.

Yes, there is a small difference.

• Wacht even = wait a moment / hang on
  This is very common and often sounds a bit softer.
• Wacht nog een seconde = wait another second
  This is more specific and focuses on a short extra amount of time.

In real conversation, even is extremely common because it often makes commands sound less abrupt.

Not necessarily, but Wacht by itself can sound direct, just like Wait in English.

Tone and context matter a lot. If you want to sound softer or more polite, Dutch often adds words like:

• even = a moment / just
• alsjeblieft = please

For example:

• Wacht even. = Wait a moment.
• Wacht nog even. = Wait just a little longer.
• Wacht nog een seconde, alsjeblieft. = Wait another second, please.

So your sentence is natural, but it can sound a bit direct if said sharply.

A simple learner-friendly pronunciation would be:

vakht nokh un suh-KON-duh

A few useful notes:

• w in Dutch sounds more like an English v
• ch in wacht is the guttural Dutch sound
• g in nog is also guttural in standard Dutch
• een is often pronounced like a reduced un in normal speech
• seconde has stress on the second syllable: se-CON-de

Yes, absolutely.

These are all natural, with slightly different nuances:

• Wacht nog een seconde. = Wait another second.
• Wacht nog een moment. = Wait another moment.
• Wacht nog even. = Wait a little longer.
• Wacht even. = Wait a moment.

Seconde is very short and specific. Moment is a bit more general. Even is very common in everyday Dutch.
