Questions & Answers about Kulta on kallista.
- kulta = the subject, gold
- on = the verb, is
- kallista = the predicate adjective, from kallis (expensive)
So the structure is:
subject + verb + adjective
Very literally: Gold is expensive.
The dictionary form is kallis, meaning expensive.
In this sentence it appears as kallista, which is an inflected form of the adjective.
Because Finnish often uses the partitive singular for a predicate adjective when the subject is a mass noun or substance used in a general sense.
Here, kulta means gold as a material, not one specific countable item. So Finnish says:
- Kulta on kallista. = Gold is expensive.
This is similar to other Finnish sentences like:
- Kahvi on kuumaa. = Coffee is hot.
- Vesi on kylmää. = Water is cold.
So kallista is not random: it reflects the fact that gold is being talked about as a substance.
