Forgive a rapid answer, as I'm far too busy examining. There's masses on the orthography of Breton. For convenience, see Janig Stephens in Routledge's The Celtic Languages. I present it in my 1986 Mouton de Gruyter grammar of Breton, confined to the 'standard' language. Several booklets, a great deal of vitriol (Per Denez, Andrev Ar Merser, etc.). Also, very sparsely but nicely and soberly presented: Jackson, in his Historical Phonology of Breton. Assimil uses a non-standard one. You have KLT, which became KLTGw (40s) and Orthographe Universitaire (50s). Also others, e.g. 'interdialectal'. KLTGw also known as 'zedacheg' because of its use of the 'ZH' digraph. Insofar as it's of any interest, I think zedacheg is more widely accepted, but it's a really painful subject. Though he's 'wrong', I sympathize with Jackson, who stated thatthe question of the orthography didn't interest him. See also my article in Multilingua (11-4, 1992: a bit dated now), another out soon in a volume dedicated to Glanville Price (U of Wales Press); am somewhat behind on a paper on Standard Breton for the Transactions of the Philological Society (a talk I gave 18 months ago). It's a fascinating subject, and perhaps one of the reasons Breton is in such trouble. --------- Ian Press, Tel: +44 71 775 3391, Fax: +44 81 980 5800 Dept of Russian, QMW Univ of London, Mile End Road, London E1 4NS, UK.
