Questions & Answers about Käytä laskinta! Sata miinus kymmenen on yhdeksänkymmentä.
Why is the command form käytä spelled with one t when the dictionary form is käyttää?
This is due to consonant gradation. To find the imperative (command) form, you can take the first person singular form (minä käytän) and drop the -n. Because the -n closes the syllable, the strong double tt weakens to a single t.
Why is the word for calculator in the partitive case (laskinta)?
How do we get the partitive form laskinta from the basic word laskin?
Nouns ending in -in, like laskin (calculator) or puhelin (telephone), follow a specific pattern. To form the partitive, the final -n changes to -nt- before adding the partitive ending -a or -ä.
Why does the word for ninety (yhdeksänkymmentä) end in the partitive form -kymmentä instead of -kymmenen?
In Finnish, multiples of ten (20, 30, 40, etc.) are formed by taking the first number and adding the partitive form of kymmenen (ten). Because it is structurally saying "nine tens", the word for ten must be in the partitive case.
