"It is your book."
Translation:Det är din bok.
Because det is not referring to the book here, it’s just a formal subject that is added to the sentence cause it needs a subject. You could say den är er bok as well, but then you’re actually like referring to something, e.g. pointing at a book and saying ”that is your book”. But here it’s just a neutral subject.
So, if you are ambiguously referring to a subject you use "det", but if you have a concrete book, it's "den"?
Not really, it's only in this starting position in the sentence. It's like the "it" in the English "It's John." We use "he" to refer to males, not "it"... but "it" doesn't actually refer to "John", grammatically. It's just a kind of special-purpose placeholder pronoun at the start of the sentence.
It's introduced very early - ninth lesson out of over sixty, before the first checkpoint.
The system is a little too lenient sometimes, this should be counted as an error. We use er for common gender nouns and ert for neuter nouns, so since it's en bok, it must be er bok if it's a book that belongs to a group of people.
How do you know if they are addressing a group of people or just one person? Because in English 'your' is for both singular and plural.
RyanED, you are correct. There is no way to tell whether it is "er bok" as in your = plural or "din bok" as in your = singular.
Whaaat? Thank you! Silly me thought it was like my/mine, your/yours, but that logic was failing me, so I came here to look for an answer and ... didn't expect this. So sily of me! Thank you
That would mean "there is your book", in the sense of "there exists a book which is yours". Anyway, this sentence is about identification, not existence.
- er is for having one en-word thing, e.g. er bok = your book
- ert is for having one ett-word thing, e.g. ert bord = your table
- era is for having multiple things, e.g. era böcker = your books
So era bok isn't grammatical.

It contains some info on that, plus a great link to a further resource.
So is there a reason to use din vs er in this context? I used din and its corret but am curious if it would accept er as well?
