OK. I have made two different posts which were both serious, but neither appeared. I guess they were not serious enough. So I must be “beyond clear” that I have an interest in Textkit. I studied Latin first in high school (2 years) then a year at the University of Arizona, and then I decided to be a Classics major and chose Greek as my specialty. I specialized in Greek tragedy, and graduated Summa Cum Laude with a B.A. in Classics. That was in 1978. In 2001, having dreamed for a long time about going back to college, I enrolled at the University of Colorado in the graduate program in Chinese, and, after five years, and with a 4.0 average, achieved a Master’s degree in Chinese. Now, in 2015, I’m renewing my interest in Classics by resuming study of Latin on my own. I’ve so far worked through Wheelock, M&F, Latin via Ovid, and now, making enthusiastic use of the Textkit key to the exercises of D’ooge’s Latin for Beginners, I’m breezing through all the exercises in that book. I want eventually to be skilled enough to read some of the more famous works of Latin literature such as the Aeneid, the Metamorphoses, the poems of Catullus, et al.
The first post that was rejected (apparently) involved a key to the long prose selections at the end of Bradley’s Arnold Latin Prose Composition. I eventually found a key to those exercises on my own. Today, I posted another short message thinking I had either 1) found an error in the Textkit key to D’Ooge’s text, or 2) I have a grave misapprehension about how the grammar should work in the simple sentence concerned. Perhaps someone will still answer that post, if it hasn’t been rejected.
I hope to be able to ask further questions here, and am quite serious about my interest in Textkit.
