However, we can make some educated guesses based on what we know about other ancient languages and cultures:
* Phoenician: Carthage was founded by Phoenicians, who spoke a Semitic language. They likely had a greeting similar to "Shalom" in Hebrew, meaning "peace".
* Punic: Carthaginians developed their own language, Punic, which was heavily influenced by Phoenician. It's possible they had a greeting specific to Punic, but we don't know what it was.
* Greek: Carthage had significant contact with the Greeks, and it's possible they adopted some of their greetings. "Χαίρε" (Chaire) was a common Greek greeting, meaning "Rejoice".
* Latin: By the time of the Roman conquest, Latin was becoming more common in Carthage. They may have used the Latin greeting "Salve", meaning "Be well".
Ultimately, we can't be certain how Carthaginians said hello. It's likely they used a variety of greetings, depending on context and social status.
