Butikken lover at levere bordet på tirsdag, hvis det stadig er på lager.

Butikken means the shop/store. In Danish, the definite article is usually added to the end of the noun instead of being a separate word like English the.

• en butik = a shop
• butikken = the shop

So Butikken lover ... means The shop promises ...

Yes, this is a very common false friend.

In Danish, at love means to promise, not to love.

• Jeg lover det. = I promise it.
• Jeg elsker dig. = I love you.

So Butikken lover at levere ... means The shop promises to deliver ...

After lover in this sentence, Danish uses the infinitive with at, just like English often uses to + verb.

• lover at levere = promises to deliver

Here:

• lover = present tense, promises
• at levere = infinitive, to deliver

So the structure is:

• Butikken lover at levere bordet ...
• The shop promises to deliver the table ...

Because bordet means the table.

Danish marks definiteness by adding the article to the end of the noun:

• et bord = a table
• bordet = the table

Since the sentence is talking about a specific table, Danish uses bordet.

In Danish, days of the week are commonly used with på when you mean on a specific day:

• på mandag = on Monday
• på tirsdag = on Tuesday

So levere bordet på tirsdag means deliver the table on Tuesday.

A useful note:

• på tirsdag usually means this coming Tuesday / Tuesday
• om tirsdagen means on Tuesdays or on Tuesday(s) in general, which is different

Hvis means if in the sense of a condition.

• hvis det stadig er på lager = if it is still in stock

This is a normal conditional clause: the shop promises delivery if the item is still available.

Learners sometimes confuse hvis with om. In many cases:

• hvis = if for conditions
• om = whether / if in indirect questions

Examples:

• Jeg kommer, hvis jeg har tid. = I’ll come if I have time.
• Jeg ved ikke, om jeg har tid. = I don’t know whether I have time.

Here det refers to the table — or more naturally, to the item being talked about.

Since bord is a neuter noun (et bord), the pronoun used for it is det.

• et bord → det

So:

• bordet = the table
• hvis det stadig er på lager = if it is still in stock

Even though English often says it, Danish also uses det here for a neuter noun.

Because this is a subordinate clause introduced by hvis.

In Danish main clauses, the finite verb usually comes early, often in second position:

• Det er stadig på lager. = It is still in stock.

But in subordinate clauses, adverbs like stadig usually come before the finite verb:

• hvis det stadig er på lager

So the pattern is:

• Main clause: Det er stadig på lager
• Subordinate clause: hvis det stadig er på lager

This difference in word order is one of the most important parts of Danish grammar.

Stadig means still.

So:

• det stadig er på lager = it is still in stock

It shows that the item may no longer be available later, but at the relevant time it might still be available.

You may also hear stadigvæk, which is a more colloquial or emphatic form of stadig:

• det stadigvæk er på lager = it is still in stock

Both are understandable, but stadig is the neutral form.

På lager is a fixed Danish expression meaning in stock.

Literally, lager is related to storage/warehouse/stock, and the whole phrase means that the item is available from inventory.

So:

• er på lager = is in stock
• ikke på lager = not in stock / out of stock

The preposition på is just the standard one used in this expression. It is best learned as a set phrase:

• at være på lager = to be in stock
