Questions & Answers about Jumătatea aceasta este mare.
Because Romanian usually puts the definite article at the end of the noun.
- jumătate = a half
- jumătatea = the half
In this sentence, the noun appears in the definite form because it is followed by the demonstrative aceasta. That is a very common Romanian pattern.
When Romanian uses this/that after the noun, the noun normally takes the definite article.
So the pattern is:
- jumătatea aceasta = this half
- cartea aceasta = this book
- fata aceasta = this girl
So jumătate aceasta would sound wrong in standard Romanian.
Yes, it can also go before the noun.
Both of these are correct:
- jumătatea aceasta
- această jumătate
They both mean this half.
A useful rule is:
- before the noun: use această jumătate
- after the noun: use jumătatea aceasta
The version with the demonstrative after the noun is extremely common in Romanian.
