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" :
Main entry: alÂ·ter
alÂ·tered; alÂ·terÂ·ing \-t(É™-)riÅ‹\
Middle English, from Medieval Latin alterare, from Latin alter other (of two); akin to Latin alius other â€” more at else
1 : to make different without changing into something else
2 : castrate, spay
: to become different
This source and others confirm my "theory." What references (published, mind you, and formal) confirm your theory?
