Questions & Answers about Prodavac meri ulje i vaga krompir.
Here, vaga is a verb: the 3rd person singular present form of vagati, meaning to weigh.
So in this sentence:
- vaga = weighs
But vaga can also be a noun meaning scale or weighing scale. Context tells you which one it is.
Compare:
- Ovo je vaga. = This is a scale.
- Prodavac vaga krompir. = The seller weighs potatoes.
Meri comes from meriti and has the broader meaning to measure.
Vaga comes from vagati and means more specifically to weigh.
So the sentence makes a useful contrast:
- meri ulje = measures oil
- vaga krompir = weighs potatoes
In real everyday Serbian, meriti can sometimes also be used where English would say weigh, so this contrast is a bit neat and textbook-like, but it is still understandable and natural enough.
Both are in the accusative case because they are direct objects of the verbs.
