Learn Finnish: Missä laukku on?

In Finnish, questions starting with a question word like missä (where) usually follow a Question Word + Subject + Verb order. You are literally saying "Where the bag is?". Saying Missä on laukku? isn't strictly wrong, but it puts heavy emphasis on the verb and sounds more like "Where exists a bag?".

The lesson teaches mikä (what) and missä (where). Are they related?

Yes! Missä is actually a form of mikä. By adding the ending -ssä (in), it literally translates to "in what?". However, in everyday language, you can just memorize it as the standard question word for "where".

Where is the word for "the" in this sentence?

Finnish does not have articles like "a" or "the". The word laukku can mean "bag", "a bag", or "the bag" depending on the context. Since you are asking where it is, it's naturally understood from context that you are looking for a specific bag ("the bag").

If I want to answer this question, how do I say where the bag is?

To answer a missä question, you usually reply with a location word that has the matching -ssa or -ssä ending (the "in" ending). For example, to say the bag is in the car (auto), you would say Laukku on autossa.
