I want to know the answer to the following question:
What was the initial difference between majuscule and minuscule letters?
All the background I'm provided with is that "According to papyrologist Knut Kleve, "The theory, then, that the lower-case letters have been developed from the fifth century uncials and the ninth century Carolingian minuscules seems to be wrong."". Is that enough to answer the question?
Answer: no
