# Transformation from Welsh (cy) to its IPA transcription (cy_FONIPA).
# Based on description of Northern Welsh in:
#
# http://en.wikipedia.org/wiki/Welsh_orthography
# http://en.wikipedia.org/wiki/Welsh_phonology
#
# Note that these rules are NOT complete: to be complete we would have to know
# the morphological analysis of the word. For example, final ‹au› is pronounced
# /a/ if it is the noun plural marker, otherwise it is /aɨ/. Similarly in
# “llongyfarch” (‘congratulating’), the morphological decomposition — “llon +
# cyfarch” — is needed to know that the ‹ng› is pronounced as /ŋg/, not as
# /ŋ/.

# Treatment of glides.
# First transduce ‹i›, ‹w› to glides prior to vowels. With ‹w› we want to
# do this also before /r,l/ after /ɡ/ (from Proto-Celtic *w) e.g. “gwlad”,
# “gwraig”. However the “after g” environment must allow for the following
# possibilities:
#
# ɡ → ŋ via nasal mutation
# ɡ → 0 via soft mutation

[ɡŋ] {w} [rl] $vowel → W;   # Plain or nasal mutation environment

# Transduce accented ‹ẃ› to ‹w›: this is used to indicate when a ‹w› that would
# normally be expected to be a glide, is instead a vowel:
