Learn Farsi: این شهر متروکه است و دیگر رونق ندارد. - This city is abandoned and is no longer prosperous.

To say 'no longer' or 'not anymore' in Farsi, you use the word digar paired with a negative verb. In this sentence, digar works with nadarad (it does not have) to literally mean 'it does not have anymore'.

The English translation says 'is no longer prosperous', but the Farsi verb is nadarad (does not have). Why?

In English, 'prosperous' is an adjective, so you use the verb 'to be'. But in Farsi, ravnaq is a noun meaning 'prosperity' or 'boom'. Instead of saying a city 'is prosperous', Farsi says the city 'has prosperity'. Therefore, the negative form is ravnaq nadarad (does not have prosperity).

I have seen the word for abandoned spelled as matruk. Why is there a final ه on matrukeh here?

This word comes from Arabic, where the ه (eh) ending is often used for inanimate nouns. In Farsi, both matruk and matrukeh are commonly used as adjectives for places like cities or buildings. You can use either one interchangeably, and they mean the exact same thing.

Does digar have to go right after va (and) in the second half of the sentence?

Adverbs like digar are somewhat flexible in Farsi, but when it means 'no longer', it generally needs to come somewhere before the negative verb. Placing it right at the start of the clause after va (and) is the most natural and common word order for this expression.
