Questions & Answers about Mikä tuo kallis laukku on?
Why is the verb on at the very end of the sentence?
In Finnish questions starting with a question word like mikä, the verb usually comes after the subject. So the word order is literally 'What that expensive bag is?'.
Why do we use mikä here instead of kuka?
You use mikä to ask 'what' about things, animals, or concepts, like the bag (laukku) in this sentence. You use kuka to ask 'who' when talking about people.
What is the difference between tuo and tämä?
tämä means 'this' and is used for something very close to the speaker. tuo means 'that' and is used for something further away, which is why it translates to 'that expensive bag'.
Does the adjective kallis need any special endings here?
No. In Finnish, adjectives must match the grammatical form of the noun they describe. Because laukku is in its basic dictionary form, kallis also stays in its basic form and sits right before the noun, just like in English.
