when is the adjective before and when is it after the noun?
I can't seem to get it straight. What is the rule for when one says "The good girl" and when is it "The girl is good?"
I studied it in seminary. I don't know where you'd be able to get lessons outside of a seminary setting, but I can at least provide the information about our textbook. We used Beginning Biblical Hebrew by Mark Futato. We also used the Brown/Driver/Briggs Hebrew Lexicon, but that's for after you've got the basics down. The Futato book also had flashcards you could use.
Editing, because we've run out of discussion space: the Futato book starts you from zero knowledge, so if you can read Hebrew, you can skim the first few chapters. The Lexicon, on the other hand, isn't meant as a textbook itself, but rather is useful for looking up the occasional unfamiliar word while reading through the Tanakh in Hebrew.
