Neologism for Farsi/Tajiki/Dari

Since language needs new words to survive & be a good tool for communication ,I guess my language needs to look at  it deeply  .

I feel my mothertongue,Farsi needs neologism ,etymology,  besides ,study of languages like Arabic,Turkish,Persian dialects ,to provide a clear panorama for neologism in Farsi  .

Besidethese afro-mentioned, we need to study Old Persian,Avestan,middle Persian,Sanskrit,Hindi,Russian,Armenian plus Hindu-europian languages ,to solve the puzzle & problem of Farsi language for futures (future people).

For example:

In Farsi is "bimaarestan" بیمارستان  "  means Hospital

In Tajik it is "bimaarkhaana" بیمار خانه

In Dari (Afghani)  "Shafaakhaana " شفاخانه
