Instructive case (original) (raw)
In the Finnish language, the Instructive case has the basic meaning of "by means of". It is a comparatively rarely used case, though it is found in some commonly used expressions, such as "omin silmin" -> "with my own eyes".
In modern Finnish, many of its instrumental uses are being superseded by the Adessive case, as in "min� k�vin junalla" -> "I travelled by train."
It is also used with Finnish verbal second infinitives to mean "by ...ing", for example "lent�en" -> "by flying", "by air".
