Questions & Answers about Við skruppum í bakaríið eftir vinnu.
Skruppum is the past tense, 1st person plural form of skreppa.
In this sentence, it means something like we popped over, we nipped, or we made a quick trip. It usually suggests a short, casual trip somewhere, not a long or formal journey.
So compared with fórum from fara (went), skruppum adds the idea that it was quick or just a small errand.
The infinitive is skreppa.
This is an irregular verb, so the vowel changes in the past tense:
- skreppa = to pop out / make a quick trip
- við skruppum = we popped out / we went quickly
That vowel change is normal for many strong verbs in Icelandic.
Yes, skruppum already tells you the subject is we, because the ending marks 1st person plural.
However, Icelandic normally still uses the subject pronoun in ordinary sentences. So Við skruppum... is the normal full form.
English learners sometimes expect Icelandic to drop subject pronouns like Spanish or Italian, but usually it does not.
