Questions & Answers about Lentäjän täytyy tarkistaa happinaamari, ennen kuin laskeutuminen alkaa.
Why is there a comma right before ennen kuin?
In Finnish, a comma is strictly required to separate a main clause from a subordinate clause. Because ennen kuin (before) starts a subordinate clause, the comma is placed immediately before it.
Why is the pilot (lentäjä) written in the genitive form as lentäjän?
This is a rule for necessive sentences. When you use a verb expressing necessity like täytyy (must), the person who has to do the action must be in the genitive case, which ends in -n.
Why isn't there an object marker (like an -n ending) on happinaamari?
This is the second half of the täytyy rule! In a sentence expressing necessity, a total object that would normally take the -n ending stays in the basic nominative form instead. So it remains happinaamari.
How is the word laskeutuminen (landing) formed?
It is built from the verb laskeutua (to land or descend). By adding the -minen suffix, you turn the verb into an activity noun, very much like adding "-ing" to "land" in English.
