What are antonym-like prefixes to the Greek "crypto"?
What is a prefix that is similar to "public", or "accessible", or "ubiquitous" such that it is harmonious with the spirit of currency needing to be of public domain, widely adopted, accessible, etc.
It doesn't have to be of Greek origin, perhaps Latin.
Solution 1:
Phanæro-, meaning "apparent".
The Cryptozoic (hidden life) was followed by the Phanærozoic (obvious life). Also cf phanærogam (visible seeds) and cryptogam (spores).
