Sanskrit,or , failing that, Hindi. Unfortunately, I can no longer retain new words. i tried studying both languages about 35 years ago and, even then, discovered that I could no longer memorise vocabulary except by excessively time-consuming repetition.Now, it just doesn't stick any more. I can remember the Latin I studied in high school in the late 1940's and the German I took in college in `1950-1951. I taught myself French and Italian in the mid-1950's, but that was long ago {sigh}.
