A small update on my new lang Euir. For starters I've found out what
"Euir" means: it consists of the clitic nominal head marker /ir/
attached to the word /Ew/ 'language', so the whole means something
like 'language of', though I don't know yet of what, although it is
probably of some place or people. It indeed looks like the dependents
of a nominal marked with /ir/ can be left implicit, which is a rather
interesting grammatical/pragmatic rule!

I have also found out some facts about allophony. The high vowel
phonemes /i y 1 u/ are realized as lax [I Y @ U] or dialectally even
high mid [e 2 @ o] -- NB /1/ is [@] in both dialects! -- except when
followed by one of the voiced semivowels/fricatives /j H G w/. The
homorganic sequences /ij yH 1G uw/ are realized as high monophthongs.
Vowels in stressed syllables not closed by an obstruent are long.
Non-prevocalic /N/ may be realized as nasalization of the preceding
vowel. Alveopalatal consonants are allophonic realizations of alveolar
+ /j/ or /H/, although the orthography has letters for them. It is
probable that [H] does only occur as an allophone of /j/ and /w/
although these two may be neutralized where [H] occurs.
