Nabataean Arabic was the dialect of Arabic spoken by the Nabataeans in antiquity.
In the first century AD, the Nabataeans wrote their inscriptions, such as the legal texts carved on the façades of the monumental tombs at Mada'in Salih, ancient Ḥegrā, in Nabataean Aramaic.
The Nabataeans, also spelled Nabateans (/ˌnæbəˈtiːənz/; Nabataean Aramaic / Nabataean Arabic: 𐢕𐢃𐢋𐢈, romanized: NBṬW, vocalized: Nabāṭū; Arabic: الأنباط, romanized: al-ʾanbāṭ), were an ancient Arab people who inhabited northern Arabia and the southern Levant. Their settlements—most prominently the assumed capital city of Raqmu (present-day Petra, Jordan)—gave the name Nabatene (Ancient Greek: Ναβατηνή, romanized: Nabatēnḗ) to the Arabian borderland that stretched from the Euphrates to the Red Sea. The Nabateans emerged as a distinct civilization and political entity between the 4th and 2nd centuries BC, with their kingdom centered around a loosely controlled trading network that brought considerable wealth and influence across the ancient world.
Described as fiercely independent by contemporary Greco-Roman accounts, the Nabataeans were annexed into the Roman Empire by Emperor Trajan in 106 AD. Nabataeans' individual culture, easily identified by their characteristic finely potted painted ceramics, was adopted into the larger Greco-Roman culture. They converted to Christianity during the Byzantine period. They have been described as one of the most gifted peoples of the ancient world and one of the "most unjustly forgotten".
