vanta (to lack / need)

vanta means "to lack" — and in practice it is how Icelanders say "I need" when they mean something is missing: I'm short of money, I'm missing two pieces, I need a hand. Its signature is the double accusative: the person who lacks something is in the accusative (mig, þig, hann…), and the thing that is lacking is also in the accusative. The verb sits frozen in the 3rd-person singular vantar, regardless of who lacks what or how many things are missing. Mig vantar peninga is literally "[it] lacks-me money." Nothing in English prepares you for two accusatives and no nominative at all — which is exactly why this verb is worth its own page.

The double-accusative paradigm

There is no person conjugation: vanta never changes for the person of the lacker. You vary the accusative experiencer, and the thing lacked is also accusative. The verb stays vantar (present) / vantaði (past) throughout — even when the thing lacked is plural.

Why two accusatives? The "lack" comes over you

The double accusative looks alien but follows the impersonal logic: lacking is a state that befalls you, so the experiencer takes an oblique case (accusative), and vanta simply happens to assign accusative to its complement as well. You are not the agent and the missing thing is not a nominative subject — both are caught up in the event. Don't fight it; learn mig vantar + accusative thing as a single fixed frame.

In real use: "I need" when something is missing

vanta is the verb you reach for when the need is a gap to be filled — a missing ingredient, an absent person, not enough money or time. It is everywhere in shops, kitchens, and logistics.

Notice the first sentence above also shows the dummy það option: það vantar mjólk ("there's milk missing / we're out of milk"), used when there is no specific experiencer in focus.

vanta vs þurfa

Both can be translated "need," but they cover different ground. vanta = something is missing / lacking (a gap), with the double-accusative frame and no infinitive. þurfa = you need to do something, or need it as a requirement, and it normally takes að + infinitive with a normal nominative subject. Mig vantar pening ("I'm short of money") vs ég þarf að vinna meira ("I need to work more").

The famous error: *mér vantar (þágufallssýki)

You will hear many native speakers say mér vantar — with the experiencer in the dative instead of the standard accusative mig vantar. This is the celebrated þágufallssýki ("dative sickness"), a long-running drift in spoken Icelandic where dative-subject verbs pull accusative-subject verbs into their orbit. It is extremely common and not stigmatised the way it once was, but it is still non-standard: in writing, exams, and careful speech, the correct form is mig vantar. Recognise mér vantar so you understand people; produce mig vantar so you're correct.

Common Mistakes

Key Takeaways

• vanta is impersonal with a double accusative: the lacker is accusative (mig) and the thing lacked is accusative too (mig vantar peninga).
• The verb is frozen at 3sg vantar / vantaði / vanti — it never agrees with the thing lacked, even in the plural.
• The forms ég vanta / við vöntum do not exist; never give vanta a nominative subject.
• mér vantar is widespread spoken þágufallssýki but non-standard — the correct subject is accusative mig.
• Use vanta for "something is missing"; use þurfa að for "need to do something."
• Auxiliary is hafa: mig hefur lengi vantað… "I've long been missing / needing…"
