I ran across this word while reading Dervla Murphy’s Full Tilt: Ireland to India with a Bicycle.
purdah: seclusion of women from public observation among Muslims and some Hindus especially in India (Merriam-Webster).
I was surprised to learn that purdah isn’t only an Islamic practice and it predates ISIS, the Taliban.
