Blame the marketing geniuses of the 1930s. When orange-fleshed sweet potatoes were introduced in the U.S., farmers needed a way to tell them apart from the paler variety. So they borrowed the word “yam” from African slaves, who called the real thing nyami. The name stuck, and now we have a whole generation who thinks a yam is just a sweet potato with a tan.
It’s like when your friend insists they’re drinking “champagne,” but it’s really just sparkling wine from Ohio. It works in conversation, but a purist will side-eye you. Still, nobody’s getting hurt—except maybe the yam’s reputation.
