I want to know the answer to the following question:
Attic Greek developed into what lingua franca?
All the background I'm provided with is that "The language of Philip II's and Alexander's court and army (which was made up of various Greek and non-Greek speaking peoples) was a version of Attic Greek, and over time this language developed into Koine, the lingua franca of the successor states.". Is that enough to answer the question?
Answer: yes
