Learn Swedish: Vi vill se de allra sötaste djuren! - We want to see the very cutest animals!

The word allra is used to make a superlative adjective even stronger. While sötaste means cutest, adding allra makes it the very cutest or the cutest of all. It always goes directly in front of the superlative adjective.

Why does the adjective sötaste end in an -e here instead of being just sötast?

Because it is in the definite form. When you say the cutest animals, you are talking about specific animals. In Swedish, a superlative adjective gets an -e at the end when it is part of a definite phrase, which means it follows words like den, det, or de.

Why are there two markers for the word the in this sentence (de and the -en in djuren)?

This is a classic example of the Swedish double definite rule. If you just want to say the animals, it is simply djuren. But as soon as you add an adjective before a definite noun, you must also add a freestanding article before that adjective. Since the noun is plural, we use de.

How should I pronounce de in this sentence?

Even though it acts as a plural article here rather than the pronoun they, de is still pronounced as dom in everyday spoken Swedish.
