Tense and Mood
The leftmost preverbs have to deal with tense, sequencing and mood. The tense preverbs aren't much used, though the future, ivi is most likely to be seen of the bunch. Much more frequent is wil, which indicates sequencing, "and then, and next" and the like. Two of the preverbs are involved in conditional sentences, which I will save for a different post.
After the tense and mood preverbs come a set of preverbs with various adverbial senses. One I pilfered from, I think, Wiyot, is diwáa on arrival:
|Then when he arrived he spoke to me.|
Another good one of this set is haaz, which indicates senses like in vain, it isn't so, it didn't really happen. In the perfective, it indicates a thwarted expectation:
|It was supposed to rain (but didn't).|
One of this set, sa' has branched out into interesting territory. It's base meaning is of proximal deixis, in time, place or discourse, here, thus, there. It has developed to also assert narrative integrity, asserting that the statement fits into the conversation. This is useful for propping up unexpected information.
|Then she threw the book (really!).|
Note in the example above the location of the direct object, ákan. If she had tossed something animate, it would occur before wil.
This is a more motley set of adverbial senses, and I anticipate more appearing over time. Many of these describe path and location: cháa for horizontal motion, kwee apart, separating, zót away, but more exotic senses appear as well, such as e'ar leaving a detectable trace or path.
|We returned against our will.|
One of my current favorites is chaash, which says that an action took place out in precipitation,
|You will be working in the rain/snow.|
The exact nature of the weather will depend of course on the season. I have also been giving metaphorical extensions to some of the simpler senses. For example, ta'ii means to completion, fully, to exhaustion, but has been extended to be practically a marker of attitude, conveying weariness.
