I'm reading and enjoying Thompson
's grammar. He also has a reduced version called An Elementary Greek Syntax. https://archive.org/details/anelementarygre00thomgoog
The thing I really like about Thompson
is that he often flips things. Instead of the traditional grammar pattern of telling you the many ways you ought to translate this GREEK into ENGLISH, he comments about how this ENGLISH can be translated into GREEK. It's like a basic grammar with composition notes.
I've culled more tips on communicating in Ancient Greek from him than many other grammars.
Below are images showing two examples. I just love the first example. It was many moons before it occurred to me that μη + the Aorist Imperative just doesn't make sense, and likewise μη + the Present Subjunctive. His comment about μη + the 3rd Person AORIST Imperative is intriguing. Could it be that the 3rd Pers Present Imperative was just so rarely used that it slipped in? But, that's minutia.
The main point is, this is striking me as a very useful grammar. Maybe someone can do an OCR on this book (especially the Syntax of Attic Greek book) and make it more accessible to us.
