Questions & Answers about Ideea este bună.
Because the basic noun is idee = idea, and the definite article -a is added to the end:
- idee = idea / an idea
- ideea = the idea
When -a is attached to idee, you get ideea, so the double e is just the result of that combination, not a typo.
It is pronounced with both vowels sounded: roughly i-de-ea.
In Romanian, the definite article is usually attached to the end of the noun, instead of being a separate word in front of it.
So:
- idee = an idea / idea
- ideea = the idea
That means Ideea este bună literally looks like idea-the is good, but in natural English it means The idea is good.
