Abraham and his father were from the southern city of Ur which was a non semetic city state.

Very true.

But by the time Abram and his father were in Ur, it was an Akkadian speaking area and Abram and his father were (at least in the Bible) thought to be Semitic by virtue of his lineage back to Shem.

Maybe. What we know is that Abraham’s father left Ur during its final collapse and its takeover by the Semitic Akkadians. No one knows whether the departure of Abram’s father came before or after the collapse.

But consider—if Abram’s father was a semetic Akkadian—why leave UR?
