What is my great-uncle's grandchild to me?

Your great-uncle's grandchild is your second cousin. Your great-uncle is your grandparent's brother, and their grandchild sits two generations further down the same line. That puts you both three generations below your shared great-grandparent, so you are second cousins — relatives of the same generation.
