Great source of Akkadian.
My speculation would be that Canaan's elite was either Akkadian, or at least they were educated/influenced from there. This is also aligned with the Biblical stories that mythical Abraham come to Canaan from Mesopotamia/Sumer.
--
"Canaan's elite was either Akkadian" -- the writing was done by scribes, who were a kind of elite, but the kings did not write these themselves.
The language is Akkadian, with heavy influence from the Canaanite of the authors.
you cut out the rest of the sentence, and then just rephrased it ;)
"or at least they were educated/influenced from there"
