* Egyptian: As a pharaoh of Egypt, Cleopatra would have spoken the Egyptian language, likely in its Late Egyptian form, the language of administration and high society at the time.
* Greek (Koine): The official language of the Ptolemaic Kingdom was Koine Greek, a common dialect of Greek that was spoken throughout the Mediterranean world during the Hellenistic period. Cleopatra was certainly fluent in Greek.
* Possibly other languages: It's highly probable that Cleopatra spoke other languages as well. She was known for her diplomacy and cultural understanding, so she may have spoken some dialects of the languages of other nations within the Ptolemaic realm, like Nubian, or even languages of her allies and rivals (e.g., Latin, Aramaic).
It's worth noting that we don't have any direct evidence of Cleopatra speaking any language other than Greek. However, her political and personal life suggest that she was multilingual, and the practice of multilingualism was common among educated elites in the ancient world.
