I kind of promised to explain, what I/we think we know about these
class A and
class B things Mr. Peterson uses. I'm not sure when or how this information will be on the wiki, so meanwhile this gotta do.
These classes are simply declination patterns. There are no wider semantical or grammatical implications. If you meet an inanimate noun in its dictionary form (ie. in nominative case), you can't easily infer, what the accusative will be - the accusative will either get an /-e/ suffix or it will not. To inform us, whether or not the /-e/ will be added, David began using
class A (/-e/ will not be added) and
class B (/-e/ will be added) markings. This is pretty much the whole deal.
It seemed at first that this /-e/ suffix was just a phonotactical thing. If the regularily derived accusative ended in a consonant or consonant cluster that was impossible for the end of the word (agaist the rules of Dothraki phonotactics, that is) an /-e/ was usually added. The whole issue seemed to consider only few of the inanimate words, and it seemed the only truly undeterminable accusatives were on the words with stems ending in geminates, because there the geminate was sometimes just degraded to a short consonant and no /-e/ was added. Since then it has become more and more apparent, that there are half a dozen reasons to add an /-e/ suffix, and so it seems you often can't dependably determine, if an inanimate noun belongs to class A or class B. It's best just to know.
Some unclear things:
- Are geminates the only case where class B would be required for phonotactical reasons, but class A is still sometimes used by simplifying the ending consontant?
- If the nominative of an inanimate noun ends in consonant, is it always class A noun?
- It does not make sense (to me) to use these classes with animate nouns, but verb past singulars work so similar to noun accusatives, that this kind of classification might be an useful tool for them too. But they seem so regular, using /-e/ always when phonotactics demand and never otherwise, that perhaps there is no need?
- As far as we know, we have met precisely one inanimate noun with vowel ending stem, zhalia. Are all inanimate nouns with vowel ending stems like this: extra vowel in nominative and class B?
- What are all the reasons for nouns to be on class B? There is some symmetry/rhythm stuff, some homonymity dodging, some phonotactics... what exactly?
When we first came up with these (and some other) irregularities, we decided to keep the techical stuff at minimum. As the accusative (and in verbs the past singular) is the only hard to determine case, we decided to simply list it as a supporting declination instead of some techical coding. When David introduced these class markings, we thought we'd just keep the vocab as it was. It might be a time for a change, either to David's marking system, or to double system, with both support declinations and David's markings.
