Questions & Answers about Giá lên.
Yes. It is a perfectly natural short sentence.
Vietnamese often allows very compact sentences when the context is clear. In Giá lên, giá is the topic/subject-like element, and lên functions as the predicate meaning go up / rise.
So the structure is basically:
- giá = price
- lên = go up, rise
English usually needs something like The price is going up or Prices are rising, but Vietnamese can say the same idea with just two words.
It can cover either idea, depending on context.
Vietnamese nouns usually do not change form for singular vs. plural. So giá can mean:
- the price
- prices
- the cost of things
- market prices in a general sense
In a sentence this short, English may translate it as either:
- The price is going up
- Prices are going up
The surrounding context tells you which is most natural.
