Questions & Answers about Șoferul explică ideea.
Because Romanian usually puts the definite article at the end of the noun instead of using a separate word like English the.
- șofer = driver
- șoferul = the driver
The ending -ul is the masculine/neuter singular definite article here.
For the same reason: Romanian often attaches the to the noun.
- idee = idea / an idea
- ideea = the idea
In this case, the definite article is -a, added to the feminine noun idee.
Because the base noun is idee, and when the definite article -a is added, the spelling becomes:
- idee
- -a → ideea
So the double e is not random; it comes from the noun itself plus the article. It is pronounced in separate syllables, roughly i-de-ea.
