Unregelmäßige Verben: fara, koma, geta, vilja

Many of the verbs you need first are strong verbs: instead of a regular set of endings, they change the vowel of the stem in the singular. English has the same idea in the past ("sing, sang"); Icelandic shows it already in the present.

Look at the two halves of the table. The singular is where the surprises are: a new vowel (fara → fer, koma → kem), no ending for "I", and -ur, -ð, -r or nothing at all (hann fer) for "you" and "he/she". The plural is built on the infinitive with the endings you know from regular verbs, -um, -ið, -a; only förum shows the ö that -um brings.

Vilja (want) has its own pattern

Vil with one l is "I want", vill with two is "he/she wants". The -t of "you" also turns up in mátt (you may) and þarft (you need).

In use

• Við förum í sund á laugardögum. - We go swimming on Saturdays.
• Ég kem frá Skotlandi. - I come from Scotland.
• Sérðu norðurljósin? - Can you see the northern lights?
• Viltu kaffi? - Would you like some coffee?

As with ertu, the "you" form fuses with þú in questions: ferðu, kemurðu, sérðu, viltu. Note also that fara covers English "go" by any means, walking, driving or flying: Ég fer til Akureyrar á morgun.
