Breakdown of Ég giska á að veðrið verði betra á morgun.
Questions & Answers about Ég giska á að veðrið verði betra á morgun.
They are doing two completely different jobs:
- giska á is a fixed verb phrase meaning to guess / to reckon / to suppose
- á morgun is a time expression meaning tomorrow
So in:
- Ég giska á = I guess / I’m guessing
- á morgun = tomorrow
Even though both use á, they are not related grammatically in the sentence.
Here að introduces a subordinate clause, much like that in English:
- Ég giska á að ...
- I guess that ...
In natural English, that is often omitted, but in Icelandic að is normally kept in this kind of sentence.
So the structure is:
- Ég giska á = main clause
- að veðrið verði betra á morgun = subordinate clause
