language_DWARF has two words for "one":
[T_WORD:ONE:lod]
[T_WORD:ONE_PREF:nir]
I assume that PREF means prefix, so I am uncertain which I should pick to be my numeral 1. Perhaps nir is the number while lod is a nonspecific pronoun (e.g. one never knows what life may bring)? However, that would break the no pronouns rule, so that doesn't fit the codification. I'm not sure what to do with this. What do you think the difference between nir and lod should be?
Now this is definitely a conundrum we got ourselves in. Let us think of what information we have:
Lod means one and is a noun.
Nir- means one and is a prefix.
Uthar means first and is a noun.
This means that in dwarven you can say "One" by itself, and it is a word on its own. But you can also say "One-[thing]" which sounds like... An adjective, but for some reason it is listed as a prefix and not an adjective. And we have First, which like English First is different from One.
This is what we have to go with...
Well, we have made it a principle of the language that words can be prefixed as an adjective. So Keshamkun means Curious cat. Nirkun would then mean One cat. Maybe Lod is used as a place holder when you want to adjectivize something WITH one (yes, kinda like a pronoun, but only used with an adjective, like Kironlod, Holy One). It is the only way I can think of to make sense of it. But I also think it can be useful so as to distinguish between someone who DOES something and someone who IS something. For example Ùdosîm could mean "Someone who makes wisdom" (which can be translated maybe as a very polished and polite word for Teacher or Author) while Dosîmlod would literally mean Wise One. Someone who IS wise. (It also permits us, funny enough, to translate Toady One's name to Dwarfish: Nodlod).
