Questions & Answers about Það er alveg kalt úti.
A natural word-by-word breakdown is:
- Það = it
- er = is
- alveg = quite / really / completely
- kalt = cold
- úti = outside / outdoors
So the sentence is built very similarly to English: It is really cold outside.
In sentences about weather, general conditions, time, and similar ideas, Icelandic often uses það as a dummy subject, just like English uses it in it is cold.
So in this sentence, það does not refer to a specific thing. It is just there because the sentence needs a subject.
This is very common in Icelandic:
- Það er kalt. = It is cold.
- Það er heitt. = It is hot.
- Það er dimmt. = It is dark.
