Questions & Answers about Dieses Dokument ist unklar.
Dieses is the German equivalent of English this (pointing to something near in space, time, or context): this document.
However, German dieses can sometimes also be translated as that in English, depending on context and what sounds more natural:
- Dieses Dokument ist unklar. → This document is unclear. (most literal)
- In some contexts: That document is unclear. (if English prefers that there)
So the basic idea is: dieses = this (one here).
