TIL about that word: Ghorbat. It is a Persian term signifying the state of being a stranger, alienation, or homesickness, often describing the emotional pain of being far from home.
Ghorbat runs through Persian poetry the way longing runs through blues music, not as a subject that appears now and then but as the key in which everything is written. Centuries of invasion and exile carved the word into the language. The poetry evolved to hold the things displaced people could not take with them.
