The KPT change or consonant gradation is a topic that hardly ever causes any joy in students. The consonants just seem to come and go as they want, and there's already enough annoying rules to remember.
In short, it's all about the syllable structure:
- If a syllable ends with a vowel, it's open, and there's a strong grade in the beginning of the syllable.
- If a syllable ends with a consonant, it's closed, and there's a weak grade in the beginning of it.
Here's a link where you can check out
which consonant combinations change and how.
The change happens only when the consonants are
between the two last syllables of the word when the word is in the basic form. (Of course, knowing how the Finnish words are divided into syllables is another story.)
I'll demonstrate with kuppi, where pp alternates with p.
- kup-pi = a cup (Strong grade in the beginning of an open syllable.)
- 2 kup-pi-a = two cups (Strong grade in the beginning of an open syllable.)
- ku-pit = cups (Weak grade in the beginning of a closed syllable.)
- ku-pis-sa = in a cup (Weak grade in the beginning of a closed syllable.)
- kup-piin = into the cup (Wait. Here it goes differently, but why? Well, it used to be kup-pi-hin, and still is in some dialects. The syllable used to be open, so that's why there's a strong grade.)
This is also explained in
Kielen elämä,
a book about the history of Finnish language in easy Finnish.
(Notice that
it goes differently if a word ends with is, as, ton, or e, but I don't have a post about that yet.)
Remember that the consonant change only occurs with
k, p and
t. Don't try to apply it to all consonants, no matter how excited you get about it.
Here are some sentences organized according to whether the grade is strong or weak. The example word is
sänky, a bed.In singular, the strong grade is used in these four cases:
- nominative: Tämä on mun sänky. - This is my bed.
- partitive: Minulla ei ole vielä sänkyä. - I don't have a bed yet.
- illative: Mennään sänkyyn! - Let's go to bed!
- essive: Käytän tätä riippumattoa sänkynä. - I use this hammock as a bed.
All the other cases have a weak grade:
- genitive: Ostin uuden sängyn. - I bought a new bed.
- inessive: Kummassa sängyssä sinä haluat nukkua? - In which (of these two) beds do you want to sleep?
- elative: Ota lakanat pois sängystä. - Take the sheets off the bed.
- adessive: Ei saa hyppiä sängyllä! - No jumping on the bed!
- ablative: Tule alas sängyltä. - Come down from the bed.
- allative: Älä laita kenkiä sängylle. - Don't put the shoes on (to) the bed.
- translative: Oho, luulin tätä mun sängyksi. - Oops, I thought this was my bed.
With plural, the nominative is weak and the genitive is strong.
Strong grade:
- partitive: Onko teillä kerrossänkyjä? - Do you have bunk beds?
- genitive: Tarkista, onko sänkyjen alla mikrofoneja. - Check if there are any microphones under the beds.
- illative: Menkää omiin sänkyihin! - Go to your own beds!
- essive: Suomessa käytetään pahvilaatikoita vauvansänkyinä. - In Finland, they use cardboard boxes as baby beds.
Weak grade:
- nominative: Pedatkaa sängyt! - Make the beds!
- inessive: He nukkuivat eri sängyissä. - They slept in separate beds.
- elative: Hotellivieraat valittivat sängyistä. - The hotel guests complained about the beds.
- adessive: He olivat tanssineet sängyillä. - They had been dancing on the beds.
- ablative: Lapset olivat hyppineet sängyiltä sohville. - They had been jumping from the beds to the sofas.
- allative: Sängyille oli läikkynyt punaviiniä. - Some red wine had spilled on the beds.
- translative: Kenen sängyiksi te luulitte näitä? - Whose beds did you think these were?
Notice that with some words, both grades are possible in partitive and illative cases:
- laatikko > laatikkoja / laatikoita - boxes
- mansikka > mansikoihin / mansikkoihin - into strawberries
And yes, I left out he weird cases. Feel free to come up with practical examples with
One more thing: Notice that
sänky is
actually pronounced
[säŋky]. The weak grade
ng is pronounced as in
sängyssä,[säŋŋyssä]. It's called
velar nasal.
