Syriac is the Aramaic dialect of Edessa in Mesopotamia. This work presents the language both in the Syriac script and in transcription. Here, the majority of the sentences in the exercises are taken directly from the P'itta, the Syriac translation of the Bible. It also gives a chart of correspondences among Arabic, Hebrew, and Syriac.
Massive errors in this--but it is extremely helpful to have. Particularly when working through Thackston's grammar totally on your own (something that I wouldn't wish upon my worst enemy).
