Questions & Answers about Við förum í ferðalag á frídögum.
Við means we. It is the nominative plural form of the 1st person pronoun, used for the subject of the sentence.
Very roughly:
- ég – I (singular, nominative)
- við – we (plural, nominative)
Because við is the subject doing the action (going on a trip), it appears in the nominative case.
The verb is fara (to go), and förum is just the present tense, 1st person plural form:
- ég fer – I go
- þú ferð – you (sg.) go
- hann/hún/það fer – he/she/it goes
- við förum – we go
- þið farið – you (pl.) go
- þeir/þær/þau fara – they go
So við förum literally means we go. You cannot say við fara; the verb must agree with the subject in person and number, so with við you need förum.
