Questions & Answers about Opiskelijan täytyy olla hiljaa kirjastossa.
Why is the word for student written as opiskelijan with an -n at the end?
In Finnish, sentences that use täytyy (must / has to) require the person doing the action to be in the genitive case. This means we add an -n to the end of the basic word opiskelija to make it opiskelijan.
Will the verb täytyy change if there is more than one student?
No, täytyy is a special verb that always stays in this exact form. It never takes personal endings like other verbs do. Instead of changing the verb, Finnish relies on the genitive subject (like opiskelijan) to show who must do the action.
Why do we use the basic dictionary form olla here?
Because it follows the obligation verb täytyy. Just like in English where we say "must be" instead of "must is", the second verb in a Finnish verb chain stays in its basic infinitive form.
Is hiljaa an adjective describing the student?
Actually, hiljaa is an adverb meaning "quietly" or "silently". While English says "to be quiet" using an adjective, Finnish phrases it more like "to be quietly". Because it is an adverb, it never changes its ending to match the subject.
