Questions & Answers about Käytätkö usein niitä hoitoaineita?
Why are we using niitä instead of ne for 'those'?
Niitä is the partitive plural form of the demonstrative pronoun ne (those). We use the partitive case here because the verb käyttää (to use) requires its object to be in the partitive. Since you are asking about multiple conditioners, both the pronoun and the noun must be in the partitive plural.
How do we get hoitoaineita from the basic word hoitoaine?
Hoitoaine (conditioner) is a noun ending in -e. For words ending in -e, the plural stem is formed by changing the final -e to -ei-. Then, we add the partitive plural ending -ta, resulting in hoitoaineita.
Why does käytätkö only have one 't' in the middle when the dictionary form is käyttää?
This is a classic example of consonant gradation. When we conjugate käyttää for the 'you' form by adding the ending -t, the syllable closes. This weakens the strong double tt down to a weak single t, giving us käytät. Then we simply attach the question particle -kö to ask 'Do you use?'.
Is it correct to put usein at the very end of the sentence instead?
