Questions & Answers about Þessi lausn er einstök.
Þessi means this.
In Þessi lausn er einstök, it points to a specific solution: this solution.
It is a demonstrative word, like this / that in English. In Icelandic, þessi changes form depending on gender, number, and case, but in this sentence þessi is the correct form for a feminine singular nominative noun.
Because þessi adds the meaning this.
- lausn = solution
- þessi lausn = this solution
If you remove þessi, the sentence becomes Lausn er einstök, which sounds incomplete in normal Icelandic unless used in a very special context. Icelandic usually needs some clearer marking here, such as:
- Lausnin er einstök = The solution is unique
- Þessi lausn er einstök = This solution is unique
