Learn Dutch: Zij recyclen het papier immers altijd. - They always recycle the paper, after all.

The word immers acts like 'after all' or 'as we know' in English. It shows that the fact that they always recycle the paper is shared knowledge used to justify whatever was said right before this sentence.

Why does immers come after het papier?

In Dutch, specific objects like het papier often move before modal adverbs like immers. You could also say Zij recyclen immers altijd het papier, but placing het papier earlier treats it as the known topic of the conversation.

I thought time adverbs like altijd had to come early in the sentence. Why is it at the end here?

While time usually comes early, short adverbs of frequency like altijd can easily be pushed to the end of the sentence by a specific direct object like het papier and a consensus adverb like immers.

How do we pronounce a borrowed English verb like recyclen in Dutch?

You keep the English pronunciation for the root of the word and simply add the standard Dutch -en ending, making it sound like 'ree-sigh-kuh-luhn'.
