Ćwarmin: Sometimes Mandatorily Passive Verbs

Ćwarmin has a set of verbs which require passive forms whenever some requirements for the subject is violated. These requirements come in three main types, two of which relate to the animacy hierarchy. This requirement seems to be related to the inverse alignment of Ŋʒädär, but not an inherited cognate - rather, it may be due to convergence with Ŋʒädär.

1. Absolute Animacy Hierarchy Restrictions

The verb 'kill' only permits animate subjects, but can take non-animate agents, and thus has an absolute restriction on the hierarchy restriction - basically, there is a line drawn across the hierarchy which limits it. With inanimate agents, the passive is required, and the agent is in the general ablative case.

A typical example of this would be the verb 'kill', which cannot take a proper inanimate subject, so e.g.

*ilmis arbaŋ-utus kerb-i-ś
*winter killed the herd

arbaŋ ilm-erəś kerb-eśp
the herd was killed by the winter

*nəlve iś kerb-i-ś
an arrow killed him

i nəlv-erəś kerb-eśp
(s)he was killed by an arrow

Another would be 'utter/express/signal/...', which basically is the same verb as 'exhale', hifnəs.

*ədnist marćost-uc hifn-i-ś
silence expresses agreement

marćost ədnist-erəś hifn-e-kn-eśp
agreement is expressed through silence (note: -e-kn- is really the applicative morpheme -ken-, and the reason the applicative is used here has to do with the argument structure of hifn-, which really means something like 'breathe'; consider the -ken- similar to a prefixed preposition or adverb, only, it does not appear in the active forms of the verb all that often).

All  of these need to be rendered in the passive (or applicative) to be grammatical in Ćwarmin.

2. Relative Animacy Hierarchy Restrictions

With many verbs, a less animate noun cannot be subject with a verb whose object is more animate. These include any verb indicating fights (ampac, nenŋel, ćasćar - all signifying fighting), causing movement sideways or upwards (hegec - push, hegtəm - pull, salkum - lift, raise, kunkun - to shake to-and-fro, vabžum - pull in by rope, liŋbəl - to move a significant distance by pulling, žal - to carry),...

The main difference here from the previous class is that low-ranked nouns can be subjects, provided the object has lower or equal rank. Thus,

ćiriŋ kosdan-uc salkum-i-ś
the tripod lifts the tent fabric

onkup estnet-uc hegədm-i-ś
the weight pulls the rope

are permitted, but not

*onkup vond-uc hegədm-i-ś
the weight pulls the horse

which would require

vond onkup-araś hegt-eśp

3. Lexically Specified

This is an odd, but limited bunch.

mamnan -  to put a child to sleep

Only the mother of the child can be the proper subject, any other agent must be oblique.

ŋačćur  - to wear a piece of clothing

The restriction here is related to tense rather than to subject or object - non-present and non-imperative must be passive.

biəkin - to endure

Passive whenever the object is not indefinite.

luzǯar -  to praise

passive whenever the object is inanimate.
