Questions & Answers about На рынке я купила свежий редис и маленький кочан капусты для салата.

Why is it купила and not купил or купить?

Купила is the past tense feminine singular form of the verb.

• купить = to buy (the infinitive)
• купил = he bought
• купила = she bought

So this sentence tells us the speaker is female.

Also, Russian past tense agrees with gender and number, not person:

• я купил = I bought, said by a man
• я купила = I bought, said by a woman

Why does the sentence begin with На рынке instead of Я купила?

Russian word order is more flexible than English word order.

Starting with На рынке puts the setting first: At the market...

So the sentence structure feels like:

• At the market, I bought...

This is very natural in Russian. It helps frame the situation before giving the main action.
