Questions & Answers about Det är sant.
In Det är sant, det means it.
This is a very common Swedish pattern, just like English It is true. The det does not always refer to a specific thing you can point to. It can be a kind of dummy subject or general it.
So:
- Det är sant = It is true / That is true
Depending on context, English may translate it as either it or that.
Swedish main clauses usually follow the V2 rule, which means the finite verb comes in the second position.
In Det är sant:
- Det = first element
- är = finite verb in second position
- sant = rest of the sentence
This is very normal Swedish word order.
