What is the rule for adjective order?
This is from the Hound of the Baskervilles , where in Chapter 5, one of the characters is referred to as having "a black, full beard" and "a full, black beard" by two different people.
Which usage is right?
My confusion is whether the first description is good English in the first place. Or is it just Arthur Conan Doyle's literary licence? Further, most characters, including those using the descriptions above, speak good, Queen's English in the novel. This just makes me wonder all the more.
