T. H. Robinson published Paradigms and Exercises in Syriac Grammar in 1915 to meet the need for 'something of an elementary nature which should be of value to the student who takes up Syriac for the first time'. Since then, the book has met this need for generations of students. Still, teachers have recognized its weaknesses and this fifth edition is a thorough revision. Much of the old explanatory text and many of the exercises have been superseded. Some matters of grammar and pronunciation receive more systematic treatment and there are new appendices to introduce the estrangela and East Syriac scripts. In its format and level, however, the book aims to be, as before, an approachable introduction to this important language.
This was easier to get through because I can already read Syriac fluently and have a (extremely) minimal understanding of the traditional language, but still, the exercises had no key (i found one online but that one was very unreliable) and were such weird sentences that they made little sense. And I also missed translations at certain parts to properly explain the difference between tenses.
Still, it provides a thorough overview of the conjugations of the different tenses and how the placement of vowels can completely change the meaning of a verb (the very much trickier part of this language)
Fine and brief introduction. Only the occasional typo. The vocabulary and definitions, as well as the standard paradigms, are geared toward later Syriac rather than earlier Syriac, and he tends to interpret words through the lens of meaning given to the equivalent word in Latin theology -- so "favor" or "goodwill" becomes "grace" (carrying, potentially, a lot of loaded Augustinian ideas unknown to the Syriac East). Paradigms are of limited use in the later chapters (when you really need them), because the brevity of the text permits him only to present the tendencies and specific changed forms of irregular / weak verbs, rather than reproducing whole paradigms for comparison.
An instructional grammar certainly isn't exciting, but from my humble experience in Syriac this is the best learner's textbook for those who don't need an extra-digestible, kid-friendly approach such as that of Kiraz (and I don't mean to knock that approach!). To compare it more specifically to Thackston's textbook, I found that Coakley's edition is superior because it i) does not rely on distracting transliteration of vocabulary, ii) is well-structured and doesn't split up unified topics, and iii) explains the concepts adequately well and furnishes the student with good exercises. Overall, a good introduction to Syriac.
On the one hand, this breaks down Syriac into digestible bits of about 4 pages long, and if you set yourself a task of doing an exercise over one or two weeks, you can get through the book fairly quickly. However, a lot of things get glossed over fairly quickly (the most incredible one was the covering of an important feature of the language within a parenthetical remark). A good supplement to the actual grammar is to try and begin to read the Peshitta alongside it fairly early on.
The Weingreen of Syriac! In other words, it's an excellent introduction. I used this for a 6 week intensive course in Basic Syriac which I just completed at CUA this week.
