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.

    Greek antonymic prefixes might include apocalypto- (from a verb meaning "reveal") or phenomeno- (from a participle meaning "shown"), but don't count on their currency in English, or even in Greek for that matter. Feb 26, 2015 at 5:13

    In addition to 'secret', a possible translation of crypto- might be 'hidden'. Given that, it occurred to me to suggest 'gymno-', which means naked or exposed.

    Could you give examples of how you would use this? It seems to me that you don't need any prefix at all, because the unprefixed word would be interpreted as open by default.

    @Barmar I was thinking about crytpocurrencies such as Bitcoin. They are by nature difficult to access, which arguably decreases the value of the commerce it drives. So I thought, well what would be the anti-cryptocurrency?

    That makes my point: currency is the anti-cryptocurrency. You need the prefix to change the normal meaning.

Phanæro-, meaning "apparent".

The Cryptozoic (hidden life) was followed by the Phanærozoic (obvious life). Also cf phanærogam (visible seeds) and cryptogam (spores).

These are all inexact antonyms but maybe they'll help:

  • co-
  • exo-
  • hyper-
  • omni-
  • over-
  • pan-
  • per-
  • peri-
  • super-
  • ultra-
  • With, over, around, everywhere, above, throughout - these are close to the opposite of hidden or exclusive or inaccessible. Why the nay-saying to these prefixes?
