Questions & Answers about Tramvaiul este mai rapid decât autobuzul.
Because Romanian usually puts the definite article at the end of the noun, not as a separate word before it.
- tramvai = tram
- tramvaiul = the tram
- autobuz = bus
- autobuzul = the bus
The ending -ul is a very common definite article ending for masculine/neuter singular nouns.
Romanian often uses the definite singular to talk about something in a general, class-wide sense.
So:
can mean something like:
- The tram is faster than the bus
- or more generally, A tram is faster than a bus
depending on context.
This is normal Romanian usage. English often uses a/an or a bare plural for general statements, but Romanian frequently prefers the definite form.
