Questions & Answers about Hän ei rikkonut ikkunaa ehdoin tahdoin.
What exactly is the instructive plural doing in ehdoin tahdoin?
Ehdoin tahdoin is a fixed idiom meaning deliberately or on purpose. It is made up of the instructive plurals of ehto (condition) and tahto (will). The instructive case ending -in usually describes the method or manner of doing something, so literally this idiom translates to something like with conditions, with wills.
Why do the consonants change from t in ehto and tahto to d in ehdoin tahdoin?
Adding the instructive plural ending -in closes the final syllable. In Finnish, adding an ending that closes a syllable triggers consonant gradation, changing strong consonants to weak ones. Here, the strong t weakens to d.
Why is the object ikkunaa in the partitive case instead of the total object form ikkunan?
Because the sentence is negative (ei rikkonut). A strict rule in Finnish is that the object of a negative action must always be in the partitive case. If the sentence were positive (He broke the window), the object would be ikkunan.
