Questions & Answers about Við göngum kringum húsið.
Here við means we.
That is a very common point of confusion, because við can also be a preposition in Icelandic, often meaning things like with, by, or against, depending on context.
In this sentence, it is clearly the pronoun we, because it comes before a plural verb:
- Við göngum = We walk / We are walking
So the structure tells you which við it is.
Göngum is the 1st person plural present tense form of the verb að ganga.
So:
- að ganga = to walk
- við göngum = we walk / we are walking
A few present-tense forms of að ganga are:
- ég geng = I walk
- þú gengur = you walk
- við göngum = we walk
- þeir ganga = they walk
So göngum is the form that matches við.
