Did you know that adjectives go in a particular order?

I was reading an article and was fascinated to learn that the order in which we string our adjectives together has a pattern. This is opinion, size, age, shape, colour, origin, material, purpose, Noun. Mix this up and you are likely to be a speaker of English as a second language. So a big brown German dog is right but a brown German big dog sounds just wrong. Try it!
