The Nabataean block contains characters used in the Nabataean script, which was used to write the Nabataean language, an ancient Arabic dialect, in the Nabataean Kingdom (modern-day Jordan) from the 2nd century BCE to the 4th century CE. The script is an abjad, with letters representing consonants, and it is the precursor to the modern Arabic script. Nabataean inscriptions are found on monuments, tombs, and coins, providing insights into the history, culture, and religion of the Nabataean civilization..
