The Adessive Case

By now you've probably forgotten the names of the other cases we've studied so far, but don't worry - you don't really need to know what they are called, just how they are formed and what they mean. So lets press on with a new case: the adessive, or "on" case. If you want to say something is on somewhere, you add -lla or -llä to the end of the word. So, for example:

lattia - the floor
lattialla - on the floor

pöytä - the table
pöydällä - on the table

katu - the street
kadulla - on the street (although in English you would say "in the street")

Those last two emphasises a second thing - when adding a case ending a single letter t changes to a d. This is known as one of the consonant gradation rules, which we'll be dealing with later.

The adessive case doesn't just mean "on" though, it can mean "with the aid of" or "using". For example:

kynä - a pen
kynällä - with a pen

kone - machine
koneella - with a machine

Incidentally, a major Finnish manufacturer and exporter of elevators and escalators is called Kone - keep an eye out in shopping centers and offices and you might see some of their products in use...
