Re: What does ‘DeRhiya’ mean?

so are there any deRhyia flats in Mumbai?

So Madam Noorjehan was able to own a flat in Mumbai before partition. I’m reading a book on Saadat Hussain Manto, where he tells about renting a kholi (very small room) for Rs 9 per month. His income was Rs 40 per month during that time.
