Ćwarmin has some more voices beyond the passive and active, but unlike the active voice, all of them use the passive -aśp morpheme for the third person, and lack person marking for first and second person subjects. The main voices beyond passive and dative-passive are the causative (of intransitives), and the causative (of transitives). There is also a detransitive-habitual aspect-voice combination.
Morphologically, there is some overlap between the two causatives. Almost all causatives of intransitives are entirely unmarked in the present tense, as are a handful of causatives of transitives. A few entirely regular such verbs are:
taun - sit, seat
wecəm - smile, make someone smile
gaxar - laugh, make someone laugh
miler - rise, raise
colan - sink, submerge
Some intransitives that are marked in the present causative include
pəlnəm - jump
polnom - jump
kəjn - run
The few transitives that are not marked in the present causative are
taslon - leave, make someone leave
kolkor - carry, load
kolćojn - carry, send
In all other TAMs but the present indicative tense, the intransitive causative has the marker -ka(n)-/-ke(n)-, and takes either no person suffix (for 1st and 2nd person) or the passive suffix -aśp/-eśp for the third person. A more "neutral" way of describing -aśp/-eśp would be as a non-canonic voice marker, which in the absense of other markers is parsed as a passive.
The causative, further, has the causee in either the accusative or the nominative, often depending on the amount of coercion or force involved (nominative indicating less such).
The use of the causative voice is clearly and easily related to the structure of a fact: someone made someone be or do something, and that is what is being expressed. Asking someone to do something, telling them to do something, suggesting they do something, placing them in a situation where they are forced to or even prone to do something is all considered forms of causation.
A further voice marker is a sort of passive causative, which is formed by -kar(u)-/-kər(i)-. This passive causative signifies a few different meanings:
(being made to do something (subject in nominative))
doing something with little volition involved (subject in genitive)
resigning to doing something (subject in dative)
accidentally doing something (subject in genitive, aspect being punctual)
No matter the case of the subject with these forms, the congruence works similarly to the passive: -aśp/-eśp for third person, no marker for first and second person.
Usage of the passive causative is more pragmatically marked, mainly indicating that something is accidental, non-volitional or even somewhat undesirable. Sometimes there is no causer stated, and this basically communicates that there is no causer but that the whole state described by the verb is very untowards according to the speaker or the subject.
There is a further voice, the applicative. It turns a locative of any type or an instrument into a direct object. For transitive verbs, it also permits turning the object into an instrumental, although we also finds speakers that permit retaining the direct object as an accusative direct object (thus having two direct objects). The applicatives morpheme is -tak-/-tək-.
With locatives the kind of locative (that is, direction or location) correlates with the aspect of the verb.
i releś -imməś forxo -rga -tak- -aśp 3sg.def door paucal
he the doors (a few) deliver (by wagon)
he delivers all the way to the doors(paucal)
This serves to emphasize a non-patient argument or to make it available for certain syntactical operations.
