Questions & Answers about Kupuję mrożone warzywa, jeśli nie mam czasu iść na rynek po świeże.

Why is it kupuję and not kupię?

Kupuję is the imperfective form, and in the present tense it often describes a habit or something repeated.

So here it means something like:

I buy frozen vegetables if I don’t have time...

By contrast, kupię is perfective and usually refers to one completed future action:

I will buy frozen vegetables...

So kupuję is the natural choice for a general, repeated situation.

Why is it mrożone warzywa?

Because warzywa is the plural of warzywo (a vegetable / vegetable item), and the adjective has to agree with it.

• singular: mrożone warzywo would not work, because singular warzywo is neuter singular, so it would be mrożone warzywo
• plural: mrożone warzywa

Here both words are in the accusative plural, but for non-masculine-personal nouns like warzywa, the accusative plural looks the same as the nominative plural.

So:

• mrożone warzywa = frozen vegetables

Is warzywa singular or plural?
