Learn Swedish: Jag gav dig ju faktiskt aldrig den sega karamellen. - I actually never gave you the chewy candy, you know.

Yes, the order is quite strict in the Swedish midfield. Small modal particles that connect to the listener, like ju (as you know), almost always come first. Next come adverbs that evaluate the statement, like faktiskt (actually) or tyvärr (unfortunately). Finally, you place the negation or frequency adverb, like aldrig (never) or inte.

Why does the object pronoun dig come before all those adverbs? I thought adverbs usually follow the verb directly.

This is due to a rule called object shift. In a main clause, if the object is an unstressed pronoun like dig, it jumps ahead of the sentence adverbs to sit right next to the verb. If the object were a full noun phrase, it would have to wait until after the entire adverb cluster ju faktiskt aldrig.

Is ju necessary here, or is it just a filler word?

While the sentence is grammatically complete without it, ju adds important social nuance. It signals that the speaker expects the listener to already know or agree with this fact. It turns a simple statement of fact into a shared realization, similar to adding 'you know' or 'as we both know' in English.

I have heard the word seg used to describe people who are slow or tired. Why does it mean 'chewy' here?
