Du overdriver ikke, hvis du siger, at køen ved stationen var lang i morges.

Because this is a main clause, and Danish main clauses usually follow the V2 rule: the finite verb comes in the second position. After that verb, sentence adverbs such as ikke normally appear.

So:

• Du overdriver ikke = correct main-clause order

A useful comparison:

• Du overdriver ikke = main clause
• ... hvis du ikke overdriver = subordinate clause

In subordinate clauses, ikke usually comes before the finite verb.

Hvis means if. It introduces a subordinate clause:

• hvis du siger = if you say

Because it is subordinate, the word order is not the same as in a main clause. Danish does not use inversion here. So you get:

• hvis du siger
• not hvis siger du

This clause gives the condition for the main statement: you are not exaggerating, if you say...

Here at means that and introduces a content clause:

• du siger, at ... = you say that ...

After verbs like sige (say), tro (think/believe), vide (know), and similar verbs, Danish often uses at to introduce what is being said, thought, or known.

English often drops that, but Danish learners are usually safest including at.

Because Danish often marks the definite form by adding an ending to the noun.

• en kø = a queue / a line

• køen = the queue / the line

• en station = a station
• stationen = the station

This is different from English, which uses a separate word (the).

A useful extra point: if there is an adjective before the noun, Danish usually uses both a separate definite word and a noun ending:

• den lange kø = the long queue

Ved means at / by / near. So ved stationen means the queue was at the station area, not necessarily inside the building.

Compare:

• ved stationen = at/by the station, near it
• i stationen = inside the station
• på stationen = at the station / on the station premises

In this sentence, ved stationen suggests the location of the queue in relation to the station, probably outside it or around it.

Because kø is a common-gender singular noun, and after var the adjective is predicative (it comes after the verb, not directly before the noun).

So:

• køen var lang = correct

Compare the forms:

• lang = common singular
• langt = neuter singular
• lange = plural, or often before a definite noun

Examples:

• en lang kø = a long queue
• et langt tog = a long train
• de lange køer = the long queues
• den lange kø = the long queue

But after var, you get:

• køen var lang

not lange.

Because the sentence mixes present time and past time in a natural way.

• Du overdriver ikke = present; this is the speaker’s judgment now
• hvis du siger = present; this is about what you say now
• køen ... var lang i morges = past; the queue was long earlier today

So the idea is:

If you say now that the queue was long this morning, you are not exaggerating.

That is why siger is present but var is past.

I morges is a fixed expression meaning this morning or earlier this morning.

It refers specifically to the morning of the same day from the speaker’s point of view.

Examples:

• Jeg så ham i morges. = I saw him this morning.
• Det regnede i morges. = It rained this morning.

It does not literally work like in morning word-for-word in English; you should learn it as a set phrase.

Because Danish uses commas more regularly to mark subordinate clauses.

In this sentence:

• hvis du siger ... is a subordinate clause
• at køen ved stationen var lang i morges is another subordinate clause inside it

So the commas help show the clause structure.

This can feel unusual to English speakers, especially the comma before at, because English often uses fewer commas in similar sentences.

Yes. That is a perfectly natural alternative.

If the hvis clause comes first, then the main clause follows with inversion:

• Hvis du siger ..., overdriver du ikke.

Notice the change:

• Du overdriver ikke ...
• ..., overdriver du ikke.

That happens because the fronted subordinate clause takes the first position, so the finite verb in the main clause still has to come second.

Yes. The verb is at overdrive = to exaggerate.

Here:

• jeg overdriver = I exaggerate / I am exaggerating
• du overdriver = you exaggerate
• han/hun overdriver = he/she exaggerates

In this sentence, Du overdriver ikke means You are not exaggerating or You’re not exaggerating.

Even though English often uses a progressive form (are not exaggerating), Danish usually just uses the simple present form.
