I encountered this word from the reading “City Limits” by Colson Whitehead. “It’s the early seventies, so everything is filthy. Which means everything is still filthy, because that is my city and I’m sticking to it.” I never heard this word before. After I find out the definitions I finally understand why. Because mostly I use word dirty, so I never tried to see another way of saying it or in a more specific way to describe something dirty.
