I was wondering whether anyone knows the exact difference between the English suffixes -agenous and -aginous.
I believe the difference is that the first suffix has to do with describing the rough essence of what something is made up of from a physical or physics standpoint, whereas the second suffix seems more heard towards describing personal character.
However, I am not sure whether this is the right distinction. I would also like to know whether there is an online etymological dictionary resource which deals with, preferably exclusively, with such suffixes, prefixes, and possibly also infixes to the extent that infixes may exist in English (personally, I am not aware of any or never studied any in English).
Thank you for your feedback.
