So, I’ve been fiddling around with a language again. This one is a derivative of Proto-Indo-European; I don’t have a name yet. It’s not a complete thing, just some musings; but here’s a bit about first declension nouns:

The first declension is small but significant, containing many common words. All the first declension nouns feature alternations between two vowels – one used in the direct cases and one used in the oblique cases. In some cases, these alternations have been created through analogy, or recreated after sound-changes obscured the original alternation. Masculine first declensions ending with a stop also show a voicing alternation, in which the final stop or cluster is voiceless in direct cases but voiced in oblique cases – this alternation has spread by analogy from the final voicing in the nominative and vocative singulars. All first declensions – indeed, all nouns – show a vowel length alternation, with the nominative singular showing a long vowel and the vocative, first accusative and comitative singulars all showing short vowels. The remaining cases show either a long or a short vowel depending on the word – all first declension feminines show a long vowel, while most but not all first declension masculines show a short vowel.
The feminines of the first declension are often collectives or abstracts – but not always. The first declension is not normally productive, but the feminising suffix –vâ is an exception. This suffix has spread by analogy from the derivation of tōrvâ (‘wood’) from toru (‘tree’), and is now used to derive substances from objects, particularly when those substances are to be used in craft or construction. Further examples include šnōurvâ (‘sinew-matter’) from šnēur (‘a sinew’), and ōšīnvâ (‘ash-wood’) from ōšinu (‘ash-tree’). The feminine paradigm shows an interesting reconstruction in the nominative and vocative plurals, which are identical to the comitative singular, by analogy with the same identity in the masculines.
