Ginger vs Ginger Root

Does anyone know if ginger root is the same as ginger? I have a recipe with dried ginger but can only find dried ginger root. Hopefully someone knows the answer

Ginger is a root. Ginger root is ginger.

http://en.wikipedia.org/wiki/Ginger

"Ginger or ginger root is the rhizome of the plant Zingiber officinale, consumed as a delicacy, medicine, or spice."

If you write ginger too many times it doesn't look like a word anymore.
