Questions & Answers about Бабушка наготовила вкусной еды.
Why is the direct object вкусной еды in the Genitive case instead of the Accusative вкусную еду?
This relates to the prefix на- in наготовила. When на- is used to show that a large quantity of something has been produced or accumulated, the verb requires its object to be in the Genitive case rather than the Accusative. This is a special partitive use of the Genitive to express a large, indefinite quantity.
What exactly does the prefix на- add to the base verb готовить? Is it just making it perfective?
It does make the verb perfective, but it also adds a specific meaning. This is an "Aktionsart" (a modification of how the action unfolds). Here, на- adds the meaning of producing a large quantity. Therefore, наготовила doesn't merely mean she finished cooking; it emphasizes that she cooked a huge amount of food.
Since наготовила already implies "cooked a lot," would it be wrong to include the word много in this sentence?
Not at all! You can absolutely say Бабушка наготовила много вкусной еды, and it is perfectly natural. Because the prefix на- combined with the Genitive case already conveys the idea of "a lot," the word много is grammatically optional. Leaving it out, as this sentence does, sounds very native and idiomatic.
Could we use the plural form of the word food here, like наготовила вкусных ед?
