Questions & Answers about Näöntarkastuksen tulos oli huono.
How is the compound word näöntarkastuksen built?
The base word is näöntarkastus (eye exam). It is made of näkö (vision or sight) in the genitive case (näön) attached to tarkastus (check or inspection). The entire compound word then takes another genitive -n ending at the very end to connect it to the word tulos (result).
Why does the word näkö change to näön inside the compound word?
This happens because of consonant gradation. When adding the genitive -n ending to näkö, the strong consonant k disappears, leaving näön. It is very common in Finnish for the first half of a compound word to be fixed in the genitive form.
What is the actual subject of this sentence?
The subject is tulos (result), which is in the basic nominative case. The word näöntarkastuksen is simply a modifier telling us what the result belongs to. Because tulos is the grammatical subject, the adjective describing it (huono) stays in the basic nominative form to match it.
