Learn Danish: Vi har kun en bil. - We only have one car.

Both words can translate to "only" or "just," but they have different jobs. kun is used when you are strictly limiting a number, amount, or fact (like having exactly one car). bare is used more like "just" to express feelings, ease, or suggestions, such as bare rolig (just relax).

The English translation says "one car," but shouldn't the number "one" be written with an accent as én?

It is very common to write én to show you mean the number "one" instead of the article "a/an." However, the accent mark is always optional in Danish. Because the word kun (only) is right next to it, the meaning is already clear, so the writer didn't need the accent.

Since there is no accent mark on en, how do you make sure people hear "one car" and not just "a car" when speaking?

In spoken Danish, you show the difference using word stress. If you just mean "a car," you stress the noun (bil). If you mean the number "one car," you put a heavy, clear emphasis on the word en.

Why does kun come after the verb, unlike the English phrase "We only have"?

In a standard Danish main clause, the verb must be the second piece of information in the sentence. Short adverbs like kun (only), ikke (not), and altid (always) usually come immediately after this main verb.
