While I had not much trouble learning masculine and neuter (one exception was usoluco whereas I'd expect usolco), the feminine nouns seem mostly illogical to my poor mind

Nouns in -a decline perfectly regularly, however the rest are a real pain. I can't understand why 'aure' goes like: aure-aurē-aureē-aurinu-auredi-aurelu. Why aurinu and not *aurenu?
Another problem is in the plural: while feminine instr ends in -lu, the pl. instr of aure is aurē-co as if it was a masculine noun, being an anomaly among the etêialu etêiēlu aurelu and êdālu.
And the final challenge is êdi, which forms the s. instr. in -iu instead of -ilu. The pE instr. ending was -ru which evolved as -lu in Cuezi, but it seems that when the pE form was -iru, the intervocalic 'r' disappeared.
I understand that some of them are results of sound-change mechanics but I am curious if a typing mistake slipped Zompist's attention; specifically I am a bit skeptical about 'aurēco'; for the life of me I can't even guess why it's not 'aurēlu', as it should.
