A new modal particle

Ladies and gentlemen, meet lu, our new volitive/desiderative particle. Since halu = "want," I think the sound works rather well.

Lu will be helping us by translating some of the English future tense semantics, specifically when the notion of futurity involves intention or desire. According to current plans, there will be another particle (form TBD) used in making predictions and the like. Par example:

ni lu polo o ka talo la ka noni
1SG=VOL=run ABL=DEF=house ALL=DEF=mountain
"I'll run from the house to the mountain"
"I think I'll run from the house to the mountain"
"I'm planning to run from the house to the mountain"

There is a certain amount of semantic overlap with halu and a full complement clause, as in

ni halu ko polo o ka talo la ka noni
1SG=want COMP=run ABL=DEF=house ALL=DEF=mountain
"I want to run from the house to the mountain"

I guess the question is whether the focus is on the action and the futurity thereof, or on the wanting itself. Note that English blurs the lines as well sometimes -- the sentence "today I wanna run from the house to the mountain" could encode an expression of desire, but I feel like more often it would be showing intent for the future.

By the way, note that the following sentence would not mean "everyone will learn Koa" in the way we'd usually expect to interpret that phrase, but something more like "everyone's planning to learn Koa," "everyone's thinking about learning Koa," etc.:

poka i lu opi le Koa
everyone 3=VOL=learn NAME=Koa

A question for you linguists: is there a better term than volitive or desiderative for this mode? I want to highlight the intentionality more than the desire, but intentative...AHA! Conative, that's it, from cōnārī "to try". The ol' Latin's getting a bit rusty. The above interlinear, then, should read

everyone 3=CON=learn NAME=Koa

And now, how about all those other modes I need particles for?
