"باريس مَدينة مَشْهورة جِدّاً."

Translation: Paris is a very famous city.

[RomainBazo1]

Paris city is very famous. Wrong?

[husynraj]

How to know if it's Paris is a very famous city OR Paris is very famous city? Which part defines to use "a" or not?

[AmineHadji1]

In Arabic, there is no indefinite article, so no a at all. However, "Paris is very famous city" is not grammatically correct in English. "very famous city" is a noun phrase, and it needs an article.
