Explanations: A1 = illative singular vowel A2 = ending vowel in words like 'maana' A3 = second vowel in words like 'daktere' A4 = first vowel in words like 'jeptsie' E1 = first vowel in words like 'sjiellie' U2 = ending vowel in words like 'nïejte' I1 = ie in all cases except ending vowel in words like 'gåetie' I2 = ending vowel in words like 'gåetie' I3 = first vowel of many case endings I4 = ending vowel on all nouns on three syllables, like 'gierehtse' O1 = oe in all cases except ending vowel in words like 'bearkoe' O2 = ending vowel in words like 'bearkoe' U1 = first vowel in words like 'njueslie' Æ = first vowel in words like 'klihtie' Å1 = first vowel in words like 'gullie' Å2 = first vowel in words like 'gaevlie' Å3 = first vowel in words like 'gåetie' when umlauting in plural Å4 = first vowel in words like 'gåetie' when not umlauting in plural D1 = possible doubling of preceeding consonant ... more to come for sure ;)
There is one spurious issue: The D1. According to the legend, it is used for doubling the prexeeding consonant. This eems to be the case in the lexicon as well, where it is found in the Inessive Singular suffix, a suffix that has the form -sse for trisyllables and -se for bisyllables. The problem is I cannot find any D1 rule to that effect. Wherever it is, it gives us two illative suffixes for both bi- and trisyllables, in stead of the intended distribution.
Same error for gaerie
It seems it does not recognise ..ie..ie nouns. bielkie, biehkie, etc. Others work, e.g. jiekie !!??
The error could lie in the different encoding in the lexicon, cf. above. Perhaps we should have had "bE1hkI2", patterning with "jiekie".
jiekie:jE1kI2 N_IE; biehkie:bI1hkI2 N_IE; biejjie:bI1jjI2 N_IE; bielie:bI1lI2 N_IE;
