The word "isidiferous" does not seem to have a widely recognized etymology or an established origin. It is a relatively uncommon term that appears to be a combination of two Latin-derived roots: "isi-" and "-ferous".
The prefix "isi-" does not have a clear meaning in Latin or English. It might have been derived from the Latin word "is", which means "he" or "it", but this connection is uncertain.
The suffix "-ferous" is a common morpheme in English that comes from Latin "ferre", meaning "to carry" or "to bear". It is often used to describe something that produces or carries a specific thing. For example, "aquiferous" means "water-bearing" and "auriferous" means "gold-bearing".
Based on this information, "isidiferous" could be interpreted as "carrying something related to the root 'isi.
