Questions & Answers about Minä siivoan aina käsineillä.
How is the plural form käsineillä built from the basic word for glove?
The basic word is käsine. For words ending in -e, the plural stem is formed by adding an -i, making the stem käsinei-. Then we add the adessive plural ending -llä (using ä because of the front vowel ä in the root word).
The adessive case usually means "on top of". Why is it used here for "with gloves"?
While the adessive case (-lla / -llä) is often used for locations (like "on the table"), it is also used to show the instrument or tool used to perform an action. So käsineillä literally means "by means of gloves" or "using gloves".
Why does the verb siivota become siivoan here?
Siivota (to clean) is a Type 4 verb. To find the stem, you drop the -ta and add an -a, giving you the stem siivoa-. Then, you add the personal ending -n for "I" to get siivoan.
Can I say "Minä aina siivoan" to match the English word order?
It would be understood, but it sounds a bit unnatural. In Finnish, adverbs of frequency like aina (always) typically go immediately after the verb, rather than before it.
