Questions & Answers about Ég geng niður stigann.
Geng is the 1st person singular present tense form of the verb ganga, which means to walk or to go on foot.
So:
- að ganga = to walk
- ég geng = I walk / I am walking
This verb is a bit irregular, so the stem changes:
- ganga → geng
That is why you do not see ég ganga here.
In normal Icelandic, the subject pronoun is usually kept:
- Ég geng = I walk
Even though the verb form gives some information about the person, Icelandic does not usually drop subject pronouns the way some languages do. So Ég geng is the normal, natural way to say it.
Here niður means down and shows direction of movement.
So the sentence has the idea:
- Ég geng = I walk
- niður = down
- stigann = the stairs / the staircase
Together: I walk down the stairs / I am walking down the stairs.
