Questions & Answers about Kasvit, kuten levä, tarvitsevat valoa.
Does the word following kuten always take the nominative case?
Not necessarily. It matches the case of the noun it exemplifies. Here, levä is in the nominative case because it gives an example of kasvit, which is the nominative subject. If the sentence were "I like plants, such as algae" (Tykkään kasveista, kuten levästä), both would take the elative case.
The English translation says "algae" (plural), but is levä singular here?
Yes, levä is in the singular. While English often treats "algae" as a plural count noun, Finnish usually treats levä as an uncountable mass noun (like "water" or "sand") when referring to it in general.
Why is the verb tarvitsevat plural when the noun right before it (levä) is singular?
The phrase kuten levä is parenthetical, meaning it is just extra information inserted between commas. The actual subject of the sentence is the plural kasvit, so the verb must be the plural tarvitsevat to agree with it.
Why is valoa in the partitive case?
The verb tarvita (to need) requires a partitive object when the thing being needed is uncountable or abstract. Since valo (light) is an uncountable mass, it takes the partitive ending -a.
