Cadal meaning the Kingdom of Justice makes no sense, because the name is referenced multiple times to a region to the far east in the 13-14th century sources and not to a sultanate or a kingdom. It was a regional name.
I did not say that the origin of the name of the region/kingdom (Adal) came from the Arabic word (cadal), which means justice.
The word (Cadal) is of Somali origin and consists of two parts: the first part is (carro), which means ( land , sand ), and the second part is (Dir), meaning the Dir tribe,
so the meaning of ( carro Dir ) is ( land of Dir ).
But with the modification, the word became ( cad dal ) by changing the letter ( r ) to the letter ( d ), as in the word (Canjeero) , which is also pronounced ( Canjeelo).

Carro Dir → Cad Dal → Caddal → Cadal
عر در ← عد دل ← عدل
كلمة ( عدل ) هي من اصل صومالي مكونة من مقطعين : المقطع الاول ( عر ) التي تعني ( ارض ) والمقطع الثاني ( در ) اي قبيلة ( در ) الصومالية ، فيكون معنى ( عر در ) هو ( ارض الدر )
ولكن مع التحوير اصبحت الكلمة ( عر در ) الى ( عد دل ) بتغير حرف الراء الى حرف الدال ، كما في كلمة ( عنجيرو ) التي تنطق ايضا ( عنجيلو ) .
