Questions & Answers about Onko tuo outo ääni häiriö?
Why does the verb on have -ko attached to it?
The -ko ending is a question particle. Attaching it to the verb and putting it at the front of the sentence turns a standard statement into a yes-or-no question.
How would I answer "Nothing is a disturbance" using the new grammar from this lesson?
You would use the negative indefinite pronoun ei mikään (nothing). The sentence would be Ei mikään ole häiriö. Remember that mikään requires the negative verb form, so we use ole after ei.
Does ääni mean "sound" or "voice"?
It means both! In Finnish, ääni can refer to a human voice, an animal noise, or any general sound. You have to rely on context to know which one makes the most sense. Here, a "strange sound" fits perfectly.
Why is the word häiriö in the basic nominative case instead of the partitive case?
Because it describes a single, countable subject (tuo outo ääni) using the verb olla (to be). In Finnish, when you say "A is B" and both are singular and countable things, the describing word is usually in the basic nominative case.
