"Wessen Wörterbuch ist dies?"

Translation: Whose dictionary is this?

[Alina510486]

You would probably use "das" instead of "dies" when you talk to a person. And I can say that because I'm German lol

[Chaos03]

"Dies" is correct but it sounds very formal. Or old-fashioned

[Kevin876054]

If you were, for example, holding up the dictionary and asking a classroom of students this question, would "das" still be preferred to "dies" to a native speaker?

[fehrerdef]

You can use both.

What's the difference between Wessen and Wem?

[MElrayes]

Wessen indicates property (whose)
Wem is the dative form of wer (who)
Wem gehört das Buch? Es gehört mir

[eshan943679]

Wer - Nominative

Wen - Accusative

Wem - Dative

Wessen - Genitive.

[Nate896107]

Is "wessen" declinable?

[Araucoforever]

Nate, did you get an answer to your question? I found out in the dictionary that there is also "wes", "wesen" besides "wessen" so why is "wessen" instead of "wes" is beyond me.

[Chaos03]

Where did you get that from ? Maybe it is from an old version of German, but we don't have that. "Wessen" is the only word for "whose" that we have

Why is this not accepted: "to whom belongs this dictionary?"

[mrhoxha]

I think that would be: "Wem gehört das wörterbuch"

[monsieur528755]

I put whose dictionary is this and was marked wrong???

[Edward305530]

I put "whose is this dictionary?" - as is commonly heard among educated speakers - and was marked wrong. One is never sure if American English has a different book of rules.

[Ricardo739116]

English word order whose is this dictionary? Should be acceptable

[Stridsaben]

I wrote "To whom does this dictionary belong?", which was not accepted. I have also tried "Whom does this dictionary belong to?". I thought the use of "whom" was needed here...?

[fehrerdef]

Your proposals translate to "Wem gehört dieses Wörterbuch?" in German.
That's close, but not the same as the original sentence, which has "wessen" ("whose").
