Questions & Answers about Ég er hress í dag.
Hress is a bit broader than any single English word. In Ég er hress í dag, it usually combines ideas like:
- feeling well
- being in good spirits / cheerful
- being lively / energetic
So depending on context, it might best be translated as:
- I’m feeling good today.
- I’m in a good mood today.
- I’m feeling energetic today.
It does not usually mean healthy in a medical/serious sense (for that you’d talk more specifically about health), but it can suggest you’re not sick, you’re fresh and well.
