Fragment from a dedicatory inscription in Nabataean script to the god Qasiu. Basalt, 1st century AD. Found in Sia in the Hauran, Southern Syria.
The 'Nabataean language' was a
semitic language and was spoken by the
Nabataeans.
The language of the Nabataean inscriptions, attested from the 2nd century BC, shows a local development of the
Aramaic language, which had ceased to have super-regional importance after the collapse of the
Achaemenid Empire (
330 BC). The
Nabataean alphabet itself also developed out of the
Aramaic alphabet.
This Aramaic dialect was increasingly affected by the
Arabic dialect of the local population. From the 4th century AD, the Arabic influence becomes overwhelming, in a way that it may be said the Nabataean language shifted seamlessly from Aramaic to Arabic. The
Arabic alphabet itself developed out of cursive variants of the Nabataean script in the 5th century.
