Wikipedia says it's a stew.

Also: "In theory, a soup is a combination of vegetables, meat or fish cooked in liquid. A stew is any dish that's prepared by stewing - that is, the food is barely covered with liquid and simmered for a long time in a covered pot."

I said stew because gumbo reminds me of Brunswick stew.

Either way, Kiho misunderstood what dish you were talking about. You're just being a bish and splitting hairs.
