Sweet Potatoes versus Yams

Could anyone please either point me to some pictures or describe for me the difference between a yam and a sweetpotato? Are yams actually the sweeter, more orange of the two, with a thin skin--while sweet potatoes are a lighter color, almost yellow, and not quite as sweet as a yam?

I'm so confused....

Yams are a tropical-vine tuber that is popular in South and Central America, parts of Asia and Africa and in the West Indies. Sweet potatoes and Yams or simular in many ways and therefore are often confused with one another. They are in fact two different species of plants. Here in the US
sweet potatoes are often called Yams and to add even more confusion, sweet potatoes that are canned are often labeled as "Yams". True yams are rarely marketed in the U.S. and are seldom grown.
Yams are somewhat sweeter than the sweet potato but are lower in some vitamins. There are several varieties of sweet potatoes grown. Beauregard, Porta Rican, Centennial, Jewel, and Vardaman are a few. You might find a true Yam in Latin American Markets...

Hope this helps

Uncle Bob is right both names are the same in the US meaning to us just sweet potatoes and if I am right yams can get really really huge not like the sweet potatoes we get.I love sweet potatoes.

Years ago some farmers developed an orange colored variety of sweet potatoes and decided to market them as yams to differentiate them from white sweet potatoes.

In the Far East, sweet potatoes are either pale yellow or yellow and are sweet. Yams are white or purple and are rather bland. However, there is another variety which is a cross between a light yellow sweet potato and purple yam. Except for a few savoury yam dishes, both tubers are used mainly in desserts.

Edited to read sweet potatoes are either pale yellow or orange...

I love them both, but find the deeper orange color much more palatable (marketed as a "yam" at my market) than the pale yellow tuber, marketed as a "sweetpptato". It's just very confusing, but this is quite helpful. Thank you.

No yams (the real kind) in the US unless imported as an oddity, which I think I saw at Whole Foods one time.
