Learn Danish: Vi har jo allerede bekræftet reservationen. - We have already confirmed the reservation, you know.

The word jo is a modal particle used to indicate shared knowledge. By adding it, the speaker is signaling something like "as you know" or "as we agreed." It makes the sentence sound more like a friendly reminder rather than a piece of brand new information.

Why do jo and allerede come right after har instead of at the end of the sentence?

In Danish main clauses, small adverbs like jo (you know), allerede (already), and ikke (not) are placed in what we call the "central field." This means they go right after the first verb (har) and before the second verb (bekræftet).

How can I tell if "reservation" is an en or et word from this sentence?

You can look at the ending of reservationen (the reservation). Because it ends in -en, it is an en word (en reservation). As a helpful tip, almost all Danish words ending in -tion are en words!

What is the dictionary form of bekræftet?

The dictionary form (infinitive) is at bekræfte (to confirm). Here, it is in its past participle form (bekræftet) because it is paired with har to create the present perfect tense (har bekræftet - have confirmed).
