|Region||Dadān (modern al-ʿUlā)|
|Era||mid-1st millennium BCE|
The grammar of Dadanitic is still poorly understood, and while several of the following features exclude its belonging to the Arabic category, more work is required to establish its correct position in the Semitic family.
- It retains the anaphoric use of the 3rd person pronoun, hʾ.
- It does not exhibit the innovative form *ḥattay (= Classical Arabic ḥattā), but instead preserves ʿdky, probably */ʿadkay/,
- It does not level the -at ending, e.g. mrʾh */marʾah/ < *marʾat ‘woman’ vs. qrt */qarīt/ ‘town’, ‘settlement’ compare with Arabic qaryatun.
- Some dialects have a C-stem (form IV) beginning with an h- rather than an ʾ- (hafʿala instead of ʾafʿala), while Proto-Arabic seems to have undergone the change h > ʾ in this verb form.
- Variation is also reflected in the definite articles, where both h(n) and ʾ (l) are attested in the corpus.
- The special dissimilation of *ṯ to /t/ in the word ‘three’, ṯlt instead of ṯlṯ.
- The dual pronoun hmy */humay/.
Dadanitic has the same repertoire of 28 phonemes as Arabic and is the only ancient member of the South Semitic script family to use matres lectionis.
