I want to know the answer to the following question:
Who was the first Ptolemaic ruler to learn the Egyptian language?
All the background I'm provided with is that "The farther away from the Mediterranean and the lower in social status, the more likely that a colonist was to adopt local ways, while the Greco-Macedonian elites and Royal families, usually remained thoroughly Greek and viewed most non-Greeks with disdain.". Is that enough to answer the question?
Answer: no
