To me, this is not a phenomenon unique to languages designated as
conlangs.  There are many instances of intentional language creation and
permutation throughout recorded history-- prescriptivist reforms, creation
of new writing systems and other varying degrees of intentional
contrivance by groups or individuals.  Since even a designated, a
posteriori conlang is a contrived permutation of a designated natlang, the
distinction does not hold for me.  An intentional permutation is an
intentional permutation.  *Every* language has degrees of intentional

As to your thought on a priori conlang genesis being a distinguishing
feature, I find this argument to be invalid as well (And perhaps this
should have been my fourth assertion).  I do not believe that an a priori
language can exist.  All language stems from language -- even so called L1
comes from experience with the linguistic context of the learner.  Hence,
even if it is only within the mind of one individual all language is a

Just my opinion :).
