Questions & Answers about On totta, että kokeellinen aineisto on hyödyllinen.
How would we change the second clause to express that the data 'turned out to be' useful, using the verb osoittautua?
You would replace on with osoittautui (turned out to be) and change the adjective hyödyllinen to the translative case: hyödylliseksi. The verb osoittautua always requires the translative case to express the final outcome or the state something is revealed to be. The clause would become: että kokeellinen aineisto osoittautui hyödylliseksi.
Why do we use the partitive totta instead of the nominative tosi in the phrase On totta?
When creating a general 'It is...' statement without a specific subject noun (like 'It is true', 'It is hard', or 'It is cold'), Finnish uses the partitive case for the adjective as a subject complement. Totta is the partitive form of tosi (true). If you were describing a specific noun instead, you would use the nominative, for example: Tämä väite on tosi (This claim is true).
How does the suffix in aineisto help us understand its meaning?
The word aineisto (data or material) is built from the base word aine (substance, matter, or subject) plus the collective suffix -sto. This suffix is used to describe a collection or grouping of things (just like kirja becomes kirjasto for library). Therefore, aineisto represents a complete collection of material or a comprehensive dataset.
Why is hyödyllinen in the nominative case here rather than the partitive, since 'data' often feels like an uncountable mass?
While 'data' is usually uncountable in English, the Finnish word aineisto represents a specific, bounded entity (a complete dataset or corpus). Because it functions as a single, complete unit here, its describing adjective takes the nominative case (hyödyllinen). If you used a conceptually uncountable noun like tieto (information), the adjective would be in the partitive: Tieto on hyödyllistä.
