And in what language did Jesus make His last pronouncement, that ‘It is finished’? He spoke it in the language of the marketplace, in Aramaic. Incidentally, Aramaic and spoken Hebrew are close to each other and were written in similar ways for more than a century with Aramaic still retaining some of the same Hebrew letters and syntax, if old memory serves.

I think you answered your own question. There are a lot of Aramaic [and Chaldean] words in Hebrew and vice versa. They all borrowed from each other. But Aramaic was still Aramaic and Hebrew was still Hebrew.

There are a lot of French words in the English language, but it is still called English not French.

Just because Jesus used Aramaic words or phrases with the Hebrew, does not mean that the Hebrew now becomes Aramaic.

His final pronouncement was Aramaic but what language did he use to speak to John at the foot of the cross and the thief on the cross??? One of the inscriptions on the placcards was always in the language of the one who hung there --- and for Jesus and the Jews that was the Hebrew inscription. The Latin was for the Roman soldiers and the Greek was for the rest.
