Turbid is an adjective that means murky or unclear.

The Latin word turba (TOUR buh) means ‘a crowd.’ When something is turbid, it is thick and muddy like a crowd.

As a kid I often experimented with mixing up all kinds of beverages into my milkshakes, but the results were so turbid, I didn’t dare take a drink. I was no doctor, but I knew anything that murky and unclear had no business in my belly.
