Questions & Answers about Läpinäkyvä kristalliko meidän täytyy jäähdyttää?
Why is the question clitic -ko attached to kristalli instead of the first word läpinäkyvä?
The -ko/-kö clitic attaches to the exact word you want to focus on. By attaching it to kristalli (Läpinäkyvä kristalliko...?), the speaker is specifically asking if the transparent crystal is the thing to cool down (and not, say, the transparent glass). If you wanted to ask if it was the transparent crystal (instead of the opaque one), you would attach it to the adjective instead: Läpinäkyväkö kristalli...?
How would the meaning change if the sentence was Täytyykö meidän jäähdyttää läpinäkyvä kristalli?
Moving the clitic to the verb turns it into a standard, neutral yes/no question: "Do we have to cool down the transparent crystal?" By putting Läpinäkyvä kristalliko at the front of the sentence, you use contrastive focus. It implies we already know that something must be cooled down, and you are verifying if that specific thing is the transparent crystal.
Why are läpinäkyvä and kristalli in the basic nominative form here, rather than the accusative (genitive) case?
This is because of a special rule for "necessive" sentences, which express necessity using verbs like täytyy, pitää, or on pakko. When a necessive verb takes a total object (meaning the action applies to the whole thing), the object stays in the nominative form instead of the usual genitive-like accusative. Therefore, we use kristalli rather than kristallin.
The verb here is jäähdyttää. How does this differ from the similar verb jäähtyä?
Jäähdyttää is a transitive verb, meaning someone actively does the action to an object (we are cooling the crystal). Jäähtyä is intransitive, meaning something cools down on its own. If the crystal were cooling down naturally over time, you would say Kristalli jäähtyy.
