I don't really have time to chime in right now, but I can provide a couple
of definitions of a "conlex" and a "conlexist."

From Inara Tabir, the coiner of the words:

"conlex- an a priori language created with the intent to be used on a daily
basis and developed to the furthest extent possible. Conlexicist- one who
creates a conlex. Conlex(ing) (v) the act of creating a conlex. Conlexa-
plural of conlex. conlexicology, the science and art of conlexa."

On the Conlex Facebook Group, this is written on the side:

"If you have created an "a priori" language and you intend to follow it to
the furthest extent to speaking it daily and making it a part of your
everyday life, this is the place for you. Basically, this page is for the
obsessed, dedicated language creator. "

On the main Conlang Facebook Page, Andy Ayres gives this series of criteria:

"Some of the things that differentiates conlexa from auxlangs is that (a)
they are not necessarily simple or intended for a mass audience like most
auxlangs are, (b) they are the reflection of the creator's aesthetics and
beliefs, a personal language and an expression of their soul; they are not
designed essentially with the needs of secondary learners in mind, or for
the sake of facility.

Here's a list of things that distinguish a conlex that I posted some while
back when the term was once again subject to a backlash:

- That the language creator has produced a language that is an intrinsic
part of both themselves and their daily life.
- That the language can be used to discuss any topic (or that the creator
strives to make it so).
- That the language is an expression or an extension of the creator's mind
and is as much part of themselves as their mother language; that the bond
between the creator and language is such that they could never countenance
either remodelling or scrapping the language down the line. They consider
it their language for life.
- That the language creator does not see developing the language as an
isolated hobby, but part of many aspects of their life.
- That the language does not exist in a vacuum, but is an expression of a
culture/s, like natural languages are.
- That the language creator strives, and has shown commitment thereto, in
making the language as rich, as expressive and as broad as a natural
language. This is a process that will be undertaken throughout their
lifetime."  (End of quotation by Any Ayres).
