The capital of Tajikistan (the greatest former SSR) is Dushanbe, a proper noun with a fascinating etymology. In the Tajik language, dushanbe means "Monday". This is because the village was right on the Silk Road and would have a huge and opulent bazaar every Monday, so that key facet became its name. Interestingly, dushanbe is a portmanteau of two Tajik words, do, meaning "two", and Shanbe, "Saturday". Monday was two days after Saturday, so the city named after Monday is in fact a couple days premature. Both components either are from or have cognates in Persian, which would make this Indo-Iranian and thus probably from Proto-Indo-European. Fun fact: from 1921 to 1961, Dushanbe went under the name Stalinabad, the time when it underwent its greatest expansion from the village to the glorious capital it is today.
