tacka (to thank) | Swedish Grammar

tacka means "to thank." It is a perfectly regular Group 1 verb, so its forms come straight from the rule — but what makes it worth a card of its own is the little grammar that hangs off it: you thank for something with tacka för, you accept or decline with tacka ja / tacka nej, and the fixed phrase tack vare means "thanks to." The bare noun tack ("thanks") is one of the first words any learner meets; this card connects it to the verb.

Principal parts

Infinitive	Present	Preteritum (past)	Supine	Imperative	Group
tacka	tackar	tackade	tackat	tacka	Group 1

Nothing irregular happens here. The present is tacka + -r (tackar), the past adds -de to give the full Group 1 ending -ade (tackade), and the supine — the form after har — ends in -at (tackat). The imperative is the bare stem, Tacka! ("Thank!"). No vowel change, no agreement with the subject.

Use 1: tacka för — thank for something

The default pattern is tacka för ("thank for"). Unlike English, where you can "thank someone" with a direct object, Swedish most often thanks for the thing — and the person, if mentioned, follows as a direct object before för.

Tack för maten!

Thanks for the food! The fixed phrase you say after a meal — tack (the noun) + för.

Jag vill tacka för hjälpen.

I want to thank you for the help. tacka för + the thing you're grateful for.

Hon tackade oss för presenten.

She thanked us for the present. The person (oss) is the direct object; för introduces the gift.

Vi har redan tackat för inbjudan.

We've already thanked them for the invitation. har tackat — the perfect, supine after har.

Use 2: tacka ja / tacka nej — accept / decline

To accept or decline an offer, Swedish says tacka ja ("thank yes") or tacka nej ("thank no"), and the thing offered comes in with till.

Jag tackade ja till jobbet.

I accepted the job. tacka ja till — literally 'thank yes to' = accept.

Tyvärr måste vi tacka nej till erbjudandet.

Unfortunately we have to decline the offer. tacka nej till = decline, turn down.

Tackar du ja eller nej till festen?

Are you accepting or declining the party invite? Both options, each with till.

Use 3: tack vare — thanks to

tack vare is a fixed prepositional phrase meaning "thanks to / owing to." It is built from the noun tack, not the verb, and it never conjugates — vare is a frozen old subjunctive form. Learn it as one unit.

Tack vare dig klarade vi det.

Thanks to you, we made it. tack vare + person/thing = 'thanks to', credit for a good outcome.

Tåget kom i tid tack vare det fina vädret.

The train arrived on time thanks to the nice weather. A frozen phrase — vare never changes.

Common Mistakes

❌ Jag tacker dig.

Incorrect — tacka is Group 1, so the present is tackar (-ar), not *tacker (-er).

✅ Jag tackar dig.

I thank you.

❌ Tack för hjälpen — jag tackde dig igår också.

Incorrect — Group 1 takes the full -ade. The past is tackade, not *tackde.

✅ Jag tackade dig igår också.

I thanked you yesterday too.

❌ Tack för att maten.

Incorrect — tack för is followed directly by the noun, not by att. Say tack för maten.

✅ Tack för maten.

Thanks for the food.

❌ Jag tackade ja jobbet.

Incorrect — the thing accepted needs till: tacka ja till jobbet.

✅ Jag tackade ja till jobbet.

I accepted the job.

❌ Tackar vare dig klarade vi det.

Incorrect — it's the frozen phrase tack vare (with the noun tack), never the verb form *tackar vare.

✅ Tack vare dig klarade vi det.

Thanks to you, we made it.

💡

tacka is fully regular Group 1: tacka – tackar – tackade – tackat. The three patterns to fix in memory are tacka för (thank for something, e.g. tack för maten), tacka ja / nej till (accept / decline an offer), and the frozen phrase tack vare ("thanks to") — built from the noun tack, so vare never changes.
