Proto-Berber *aḍəβ pf. *uḍắβ impf. *ətt-aḍăβ 'to fold'

• Ghd. oḍəβ 'to fold'
• Niger Tuareg (WY) aḍu 'to fold'
• Ahaggar Tuareg aḍ 'to fold'
• Zng. yaḏ̣īh 'to fold'
• CMB aḍu 'to fold'
• Tashl. aḍu 'come back'
• Mzab aḍi 'to fold'

Notes:

Ghadamsi initial o usually corresponds to a root-initial *ʔ, but we would expect a reflex of this in Zénaga, which is absent. One wonders if, for whatever reason the presence of *β in the root causes a similar rounding of the initial vowel ā.
