Questions & Answers about Me siivoamme kylpyhuoneen hyvillä pesuaineilla.
How do we get the form hyvillä from the basic adjective hyvä?
To form the adessive plural, we first need the plural stem. For words ending in -a or -ä like hyvä, the final vowel changes to an -i- in the plural, giving the stem hyvi-. Then we just add the adessive ending -llä to get hyvillä.
How is the plural stem formed for pesuaineilla?
The basic word is pesuaine (detergent), which ends in an -e. When forming the plural stem for words ending in -e, we add an extra -e- before the plural -i-, creating an -ei- combination. This makes the stem pesuainei-. Add the adessive ending -lla, and you get pesuaineilla.
Why use the adessive case (-lla/-llä) to mean "with" instead of using kanssa?
In Finnish, the adessive case (-lla/-llä) is used to express the instrument or tool used to perform an action. Since the detergents are the tools being used to clean, they take the adessive case. The word kanssa is usually reserved for doing things in the company of people or animals (like "with a friend").
Why is the bathroom kylpyhuoneen instead of the partitive kylpyhuonetta?
