Briefly: an indefinite Noun Phrase is normally introduced into an English conversation or "text" with the There Be __ construction. So....
- There are nine women at the table. versus
- ? / * Nine women are at the table.
The ? indicates a sentence that is at best odd; the star (*) indicates a sentence that is ungrammatical. As a second pair of examples,
- There's a fly in my soup. 4 ?? / * A fly is in my soup.
French with "Il y a...", Spanish with "Hay...", German with "Es gibt...." and Russian with "Yest....." have somewhat similar constructions for introducing indefinite Noun Phrases. I don't think Rumanian has a similar such device, but how about it, native speakers? Is the following grammatical as a declarative sentence?
1R-?. Sint noua femei la masa. (can't get the diacritics in)
