"Při cestě domů snědla sedmnáct jablek."

Translation: On the way home, she ate seventeen apples.

[paulk1011]

Why is 'she ate' an entirely different word (snědla) than any other form or conjugation of 'eat' (i.e. jím, jíst, jedl, etc.)?

[kacenka9]

SNĚDLA (inf. SNÍST) is a perfect verb (aspect) while JÍST is imprefect. Ona jedla = she was eating. Ona snědla = she ate. The apples are gone. Some of these perfect verbs do not really exist in present tense. They only have past and future.

You can easily have a sentence MY TO JÍME (present) AŽ TO SNÍME (future tense). which would be "we are eating it till we finish it (eat it)"

[Giovanni919769]

Why is "při"and not "na" cestě? What's the difference between the two prepositions?

[VladaFu]

Both při and na are equally accepted in the reverse exercise. It is like on vs. during the way/trip home.

[JohnBraga1]

I wrote domu instead of domů and it was accepted. Should it have been?

[VladaFu]

Only as a typo or if you accept no diacritics. Otherwise it is Common Czech.
