Questions & Answers about Ég horfi í gegnum gluggann.
Horfa is the infinitive, meaning to look or to watch.
In the sentence, the verb has to match ég (I), so it changes to the 1st person singular present tense:
- ég horfi = I look / I am looking
- þú horfir = you look
- hann/hún/það horfir = he/she/it looks
So Ég horfi ... is the correct finite verb form for I.
It can mean either, depending on context.
In Icelandic, the simple present often covers both:
- I look through the window
- I am looking through the window
If you want to emphasize that the action is happening right now, Icelandic can also use vera að + infinitive:
- Ég er að horfa í gegnum gluggann.
But the shorter sentence Ég horfi í gegnum gluggann is perfectly normal.
Í gegnum means through.
It is a very common Icelandic expression and functions much like a preposition in English. In this sentence, it introduces the thing that someone is looking through:
- í gegnum gluggann = through the window
It is normally written as two words: í gegnum.
