Verbtype 6 Consonant Gradation

Verbtype 6 has consonant gradation.

1. What is Consonant Gradation?

Consonant gradation is something you’re going to run into all the time when learning Finnish. It’s something that affects both nouns and verbs, though in different ways. It’s called gradation, because words can have a ”strong” grade and a ”weak” grade. This change takes place when we add an ending to a word. For verbs this can be the personal endings (-n, -t) or any of the tense modifiers.

Consonant gradation only affects certain consonants (K, P and T). When conjugating a verb, the K, P and T in the middle of the word can change. Different verbtypes undergo a different system of consonant gradation.

In this article, we will only be looking at verbtype 6 consonant gradation. Find out more about verbtype 6 and the other verbtypes here.

2. When Do You Use Consonant Gradation?

Verbtype 6 consonant gradation takes place in all the conjugated forms of the present tense. The infinitive of the verb (the basic form) will always be weak, while every conjugated form will be strong. This is what is sometimes called ”negative consonant gradation” (käänteinen astevaihtelu).

Verbtype 6 is cool in the way that often the adjective it has beendeveloped from has the strong grade of the verb, while the verb’s infinitive is weak. Thanks to that, you’re able to predict consonant gradation if you know the adjective.

3. Which Consonants Change?

Consonant gradation only happens with the following consonants.

The question marks mean I haven’t been able to come up with a verb that fits that type of consonant gradation. This might either be due to me not thinking long enough, or because there just simply aren’t any verbs of that type.

4. Limitations on Consonant Gradation

If a certain consonant combination is not included in the list above, they’re not subject to consonant gradation. For example: -ss- is not in the list, so you will never consonant gradate -ss- to -s-.
