This rule is actually why J.R.R. Tolkien got interested in Philology, his main field of study, and subsequently wrote stories. When writing a story when he was very young, he wrote down "a green great dragon", and his mother corrected him. He was fascinated why it could not be a green great dragon and had to be a great green dragon.
