Questions & Answers about Ми прополюємо клумбу, а граблі лежать поруч.
Because клумбу is the direct object of прополюємо.
The basic dictionary form is клумба. But feminine nouns ending in -а usually change to -у / -ю in the singular accusative, which is the case used for a direct object:
- клумба → клумбу
- книга → книгу
- машина → машину
So Ми прополюємо клумбу means We are weeding the flowerbed, with клумбу in the accusative.
It can mean either, depending on context.
Ukrainian does not have a separate present continuous form like English are weeding. The present tense of an imperfective verb can cover both:
- we weed
- we are weeding
Here, because the sentence describes a scene in progress, English would most naturally use we are weeding.
Also, прополюємо is:
- present tense
- 1st person plural
- from the imperfective verb прополювати
So the ending -ємо tells you it means we.
