Questions & Answers about Pragul este lângă ușă.
Because -ul is the Romanian definite article attached to the end of the noun.
- prag = a threshold
- pragul = the threshold
Unlike English, Romanian usually does not put a separate word before the noun for the. It attaches the article to the noun instead.
In simple location phrases after a preposition, Romanian often uses the bare noun very naturally:
English may still translate these with the, depending on context. So lângă ușă can be a perfectly normal way to say by the door.
If you want to make the door more specifically identified, Romanian often adds more information, for example:
- lângă ușa din față = by the front door
- lângă ușa apartamentului = by the apartment door
So in this sentence, ușă is not strange; it is a normal locative expression.
