Questions & Answers about Kuulitko sen korkean sävelen lopussa?
-ko / -kö is the Finnish question particle. It turns a statement into a yes-no question.
- kuulit = you heard
- kuulitko = did you hear?
So Kuulitko... ? means Did you hear... ?
In Finnish, this particle is usually attached to the first important word in the sentence.
Finnish usually does not need the subject pronoun if the verb already shows who the subject is.
Here:
- kuulit = you heard
The ending -it already tells us the subject is you.
So sinä is unnecessary unless you want extra emphasis or contrast.
- neutral: Kuulitko sen korkean sävelen lopussa?
- emphatic: Sinäkö kuulit sen korkean sävelen lopussa? = Was it you who heard the high note at the end?
