Questions & Answers about Þokan er svo þykk að við keyrum hægt.
Þokan means the fog, while þoka means simply fog.
Icelandic usually adds the definite article to the end of the noun instead of using a separate word like English the.
- þoka = fog
- þokan = the fog
So Þokan er svo þykk... means The fog is so thick...
The adjective þykk has to agree with the noun it describes.
Here, þokan is:
- feminine
- singular
- nominative (because it is the subject of the sentence)
So the adjective also takes the feminine singular nominative form:
- masculine: þykkur
- feminine: þykk
- neuter: þykkt
That is why we get þokan er svo þykk.
Svo ... að means so ... that.
It is a very common Icelandic pattern used to show result:
