Is the medical prefix ana- a noun?

Answer 1

The prefix "ana-" means upon. Another form would be the prefix "epi".

A prefix does not determine if the word is a noun, adjective, verb or adverb.

You will find that designator at the end of the word.

For example:

Contagion is a noun with the ending -ion.

Acrophobia is a feminine noun with the inding "-a".

Renal is an adjective with the "-ic" ending meaning "pertaining to".

Answer 2

No, the medical prefix ana- is not a noun. It is a prefix used to indicate repetition, back, again, or against in medical terminology.
