Questions & Answers about Для каши мама купила пшено и молоко.
Because для requires the genitive case.
- Dictionary form: каша = porridge
- After для (for), it becomes каши
So:
- каша = porridge
- для каши = for porridge
This is a very common pattern in Russian: для + genitive.
Для usually means for.
In this sentence, для каши means for the porridge or more naturally in English, to make porridge.
So the idea is that Mom bought millet and milk for making porridge.

Russian verbs in the past tense agree with the subject in gender and number:
- купил = bought, masculine
- купила = bought, feminine
- купило = bought, neuter
- купили = bought, plural
Since мама is feminine, the correct form is купила.
