Can anyone comment on why it is "det næste" and not just "næste"?
Dim ond dysgwr ydw i (I'm just a learner), so I can't say why it's so. But I have noticed that while it's "Hvad er det næste?" (What's next?), very curiously it's "Hvad er næste step?" (What's the next step?)!
Think of it as being short for "det næste ting".
Would one be understood if they left out the "det"?
Yeah, I do not get why there is, set, in the sentence
In this example, the word "det" has to be written or it would be wrong like in the "jeg ved det ikke" example where you cannot ommit the object?
