The Nabatean alphabet was derived from Aramaic and written right to left. It evolved into the Arabic alphabet around the 4th century CE. The spoken Nabatean language is related to old Arabic. Despite their ability to write and speak multiple languages, the Nabateans neither recorded their history nor produced literature. Writing was limited to simple inscriptions on tombs, graffiti, and some legal documents in their late history.
