I've been (slowly) working through "Basic Greek in 30 Minutes a Day" by James Found. I picked this up at Lifeway, and I've been enjoying the fairly user-friendly introdcution to the Greek language presented in this workbook. Basically, the text is printed in a pulpy, worktext-style format where you fill in answers on most every page. The text starts out great, with very simplistic example of reading english words in greek (such as English words like "bat" written in greek characters) and slowly starts through exercises that introduce greek characters and words. The pace is nice and smooth for a linguistic dummy for me.
However, the book tends to take a deeper direction into Greek grammar around page 120+, and once you start getting into the nominative, genative stuff, my eyes start to glaze over. You know, it's not for lack of effort, but this stuff gets pretty hard! (good observation Captain Obvious!) But I'm going to keep on with this. What's remarkable is how, as you learn these words, you start to slowly (if in subtle ways) see the richness in the word usage within certain passages of scripture, as well as gaining an appreciation for semi-regular words you hear from time to time, in terms of tracing back to the Greek (scoliosis, anathema, etc, in addition to so many Biblical words).
Might be slow progress finishing this but I've enjoyed the experience so far.
