Questions & Answers about Amma vill prjóna nýja peysu fyrir dóttur mína í vetur.
Because vilja means to want / to want to, and it is followed by an infinitive.
- vill = wants
- prjóna = to knit
So Amma vill prjóna means Grandma wants to knit.
If you said Amma prjónar, that would mean Grandma is knitting / Grandma knits, which is a statement about what she does, not what she wants to do.
After modal-type verbs like vilja (want), Icelandic normally uses the infinitive without að.
So:
- vill prjóna = wants to knit
- not vill að prjóna
This is similar to English in a way, except English uses to, while Icelandic often leaves it out after certain verbs.
