Ahhh. I saw, but I saw only dimly. And I wasn't at all familiar with "yan tan tethera", but am very glad that you pointed me to it.
So, if I understand fully now, you're suggesting I do with alliteration what yan-tan does with rhyme for each pairing, and on top of that use rhyme (or assonance, at least) for the odd and even series, yes? I'm not sure how much sense that would make here, because there really aren't many plausible situation in which people would be "counting in fractions"... but I do see the underlying appeal. I still don't like "Neathing", but I could drop the initial letter of "nine" instead, and I have no objection to changing "ace" to "tace" to extend the sequence. I think it works even better with alternating lines, though:
That way, it's /a/-/ai/-/i/-/ei/ in lines one and two and again in lines three and four. That seems like a good balance between repetition-based symmetry and variation-based distinctiveness, I'd say.
And your humanoids don't need twelve fingers to count in base twelve.
Yeah, no, it's the other way 'round: They have six fingers per hand a priori
, and the counting system is the natural consequence. I actually made it a lot more messy than "base-12" suggests, with 24 to a "score", 6 scores to a "cross", and 9 cross to a "clique", as a parallel to the mix of bases often found in traditional European systems (five, ten, dozen, score)... but that needn't concern us here!
