Is the adjective in partitive case? How come?
"Ruoka" is a mass noun.
Is word order important for this one?
Well you could say it differently, but this is the most natural way of saying it
I like food
"Pidän ruoasta." (ruuasta)
"Tykkään ruoasta." (ruuasta)
vs. "Rakastan ruokaa" - I love food.
so is 'miksi on' really quite wrong?
its ok - I didnt spot the 'on' later! :) .... I thought at first miksi was without 'is'
