Questions & Answers about Etkö sinä tosiaan tiedä?
How does the word etkö work to make this a question?
To make a negative yes/no question, you attach the question suffix -kö (or -ko) directly to the negative verb. Here, et ('you do not') becomes etkö ('do you not?').
Why is the main verb tiedä instead of tiedät?
In negative sentences, the main verb drops its personal ending. Because the negative verb etkö already shows it is 'you' doing the action, the main verb just uses its negative stem. As a quick refresher on consonant gradation: the strong -t- in the dictionary form tietää changes to a weak -d-, giving us tiedä.
Since etkö already tells us who is doing the action, do we really need the word sinä?
It is grammatically optional. The negative verb et already tells us the subject is 'you'. However, including sinä in a question like this adds emphasis or surprise, as if saying: 'Don't YOU (of all people) know?'
I learned the word todella for 'really'. Is tosiaan the same thing?
Yes, tosiaan and todella both mean 'really' or 'truly' and can often be swapped. Tosiaan is very natural here for expressing surprise or disbelief.
