istunnolle
Istunnolle is the allative case form of the Finnish noun istunto, meaning a session, hearing, or formal meeting (such as a court hearing or parliamentary session). The allative suffix -lle expresses direction toward a destination and is used here to indicate going to or attending a session. It is distinct from istuntoon (illative) meaning into the session, and istunnossa (inessive) meaning inside the session. The genitive form is istunnon.
In usage, istunnolle appears in formal and institutional contexts. It is often used with verbs of motion
Notes: In everyday Finnish, people may prefer phrases like mennä istuntoon to indicate going to a session
