twenty-first century Cornish (GanS 1)

"The superior form of the language which I use, in contradistinction to the inferior form that you use". In two decades of contentious argument, many hundreds of learners have been driven away from the Language Revival, and the question of superiority is not yet resolved.

An ambiguous term which seems to denote several mutually exclusive concepts, depending on your point of view:

(1) The Laissez-fairy:
Somewhat tautologically, any form of Cornish which is spoken or written in the present century. This broad definition includes both those forms of the language which would be fairly recognisable to our ancestors (should they turn up unexpectedly in a time machine), as well as those forms which would not. This latter group includes a range of 'Cornic esperantos' such as Kemyn and Saun-dreck.

(2) The Historical Attesticle:
Any form of Cornish (such as Unified C., Late C., or their Revised versions) which bears a resemblance to what our ancestors would have written and spoken. There is some difficulty in establishing just what that would have been, as the language pretty much died out in the 19th century; but the best reconstructions have to be based on the written evidence, as that is all we have, rather than the pipe-dreams of some scholars manqué. This definition excludes fictional forms such as Kemyn, Saun-dreck, etc. as not being real Cornish.

(3) The Kemynite:
Kemyn (or Kenewek as it is often known) is the only form for the new century. All the historically-based forms of Cornish are swept aside by the new broom, and are deprecated as old-fashioned, mediaeval, dead, or as being used by 'anti-Cornish bigots who exist in a Tudor refectory culture' [sic].
(This invented form is sometimes known by its adherents simply as 'Cornish' (implying that the other forms are too worthless to count) or 'Fit-for-Purpose Cornish' and 'Easy-enough-for-Cornish-dullards Cornish').

(4) The Ivory Towerite:
21st-century Cornish is a null concept: Cornish is nicely dead, a pickled museum specimen, an ideal medium for academic dissertations because there aren't any uppity native speakers around to disagree with anything you might care to write. Speakers of the revived forms of 'Cornish' don't count, because they're not real Cornish: UC, UCR, LCR, Kemyn, Saun-dreck are all equally spurious.
However, the 'Ivory Towerite' is a curious beast, since all reports of his existence seem to be second hand: no-one ever admits either to being one or to having actually met one. He could be as mythical as most of the "92–98% of Cornish speakers" claimed by the Kemyn Klan.
