Questions & Answers about В борщ я всегда добавляю укроп и петрушку.
Борщ is in the accusative singular here, because в can mean into when it shows movement or direction.
With добавлять (to add), Russian often expresses the destination with в + accusative:
- добавить соль в суп = to add salt to the soup
- добавить сахар в чай = to add sugar to the tea
So в борщ literally means into the borscht.
Also, борщ is a masculine inanimate noun, so its accusative singular looks the same as the nominative:
- nominative: борщ
- accusative: борщ
Yes, it could be left out.
Russian often drops subject pronouns when the verb already makes the subject clear. So both are possible:
- В борщ всегда добавляю укроп и петрушку.
- В борщ я всегда добавляю укроп и петрушку.
Including я can add a bit of emphasis or contrast, something like:
- As for me, I always add dill and parsley to borscht.
So я is not required for grammar, but it can help shape the tone.
