Neos, I appreciate that you have given consideration to my critique. This is good. Open mindness is extremely important.
I would like you to consider something else: what is the
source for these interpretations of etymology? You say here that, perhaps there is one of two direct Greek origins for "alter," for example, or a Latin origin. I insist (as I believe will the majority insist) that the Latin origin is the correct one.
How do I know this?
It is the source of my understanding. I can cite this reference from Webster (and countless others, including Latin dictionaries) that demonstrate the origin of "alter" :

This source and others confirm my "theory." What references (published, mind you, and formal) confirm your theory?
