I want to know the answer to the following question:
What does the suffix -stan mean?
All the background I'm provided with is that "According to the Library of Congress's 1997 Country Study of Tajikistan, it is difficult to definitively state the origins of the word "Tajik" because the term is "embroiled in twentieth-century political disputes about whether Turkic or Iranian peoples were the original inhabitants of Central Asia."". Is that enough to answer the question?
