Käytöillä

Käytöillä is a Finnish term that translates to "by means of," "through," or "with" in English. It is a grammatical case ending, specifically an adessive case form, that indicates the instrument or method by which an action is performed. It is formed by adding the suffix "-llä" or "-llä" to the end of a noun.

For example, in the sentence "Kirjoitin paperille kynällä" (I wrote on the paper with a pen), "kynällä" is the adessive form of the noun "kynä" (pen), indicating that the pen was the instrument used for writing. Similarly, "Matkustin junalla" (I traveled by train) uses the adessive form of "juna" (train) to denote the mode of transportation.

The adessive case in Finnish is versatile and can also indicate location or presence, such as "Olen talolla" (I am at the house). However, when used to denote the means or instrument, it is often translated as "by," "with," or "through." Understanding the nuances of the adessive case is crucial for comprehending Finnish grammar and sentence structure, as it conveys important contextual information about how an action is carried out. The suffix's specific form, "-llä" or "-llä," depends on vowel harmony rules within the Finnish language.
