Questions & Answers about Onko tämä peli todellinen, vai tulenko minä hulluksi?
Why does the word hullu have the -ksi ending?
This is the translative case. In Finnish, when you become something (a change of state), that new state takes the -ksi ending. Because you are transitioning into a state of craziness, hullu (crazy) becomes hulluksi.
Wait, doesn't tulla mean "to come"? Why is it translated as "am I going"?
Yes, tulla usually means "to come". However, it is also the standard Finnish verb for "to become". While in English you say you are "going" crazy, in Finnish you say you are "becoming" crazy (tulla hulluksi).
Why use vai for "or" instead of tai?
Finnish has two words for "or". Vai is used specifically in questions where the options are mutually exclusive—you are asking the listener to pick one of the options (either the game is real, or I am crazy). Tai is used in regular statements or when multiple things can be true.
Why are there two question endings in this sentence (onko and tulenko)?
Because this sentence connects two separate yes/no questions with vai (or). The first half asks "Is it?" (onko), and the second half asks "Am I becoming?" (tulenko). Each main verb gets its own -ko suffix to show that both sides are questions.
