Some questions

[Jerry20]

Ancient Hebrew and Aramaic have quite a few common roots, but other than that they are different. Late Hebrew (early centuries AD) has adopted many Aramaic and Greek words, so they became a bit more similar. Modern Hebrew is somewhat of a mix between ancient and later Hebrew. As a native Hebrew speaker, I can sometimes understand written Aramaic text. I can barely understand spoken Aramaic though, for the same reason that Spanish speakers can't understand spoken Portuguese. In fact, certain dialects of Aramaic are so different from others that, for example, Kurdish Jews couldn't communicate with Assyrians Christians even though both spoke Aramaic.
