Time clauses (heti kun)

Sequencing Actions with heti kun

In Finnish, you can express "as soon as" using the temporal conjunction heti kun. To describe a sequence of future actions, Finnish uses a specific pairing of tenses:

  • The action completed first is in the perfect tense (e.g., olen kuorinut — I have peeled).
  • The action happening second is in the present tense. Since Finnish has no dedicated future tense, the present tense naturally expresses what you will do next.
As soon as I have peeled the potatoes, I will boil them.
Heti kun olen kuorinut perunat, keitän ne.
As soon as we have chopped the onion, we will add it to the soup.
Heti kun olemme pilkkoneet sipulin, lisäämme sen keittoon.

Flexible Clause Order

The heti kun clause does not have to go at the beginning of the sentence. The tense rule remains exactly the same regardless of order: the completed action uses the perfect tense, and the future action uses the present tense.

We will add the garlic as soon as I have fried the meat.
Lisäämme valkosipulin heti kun olen paistanut lihan.
I will taste the soup as soon as you have added the pepper.
Maistan keittoa heti kun olet lisännyt pippurin.

Kitchen Actions and Measurements

Finnish recipes often use standard volume measurements like the desilitra (deciliter) or ruokalusikallinen (tablespoonful). You can easily drop these into your step-by-step heti kun sequences alongside kitchen verbs like raastaa (to grate) and vatkata (to whip).

As soon as they have grated the cheese, the pizza will be ready.
Heti kun he ovat raastaneet juuston, pizza on valmis.
As soon as I have whipped the dough, I will bake the cake.
Heti kun olen vatkannut taikinan, leivon kakun.
I will eat as soon as I have added a tablespoonful of butter to the soup.
