Case flagging in Duriac
Many polysynthetic languages don't do a lot of case marking, especially for core referents. But there's probably a cognitive reason for this. Many of those languages happen to be V-first, meaning the information about referents is already given before they're explicitly named, reducing the need to flag case roles. Duriac is V-last so there's some utility in flagging case. However, Duriac has rules that seemingly eliminate explicit markers when they conform with what's called the
ideal core argument situation.
I use the term flagging per Haspelmath (2019). Other conventions: S = subject of intransitive verb, A = subject of transitive, P = direct object, IO = indirect object, X = applied object, term = {S, A, P}, argument = {S, A, P, IO, X}, oblique argument = {IO, X}, adjunct = non-argument NPs in an adverbial case
In Duriac, an ideal situation involves a sentient referent acting upon an inanimate referent. So:
- sentient A is always unflagged
- likewise an inanimate P is always unflagged
- animate A is flagged if the P is [EDIT] sentient (i.e. higher rank)
- animate P is flagged if the A is [EDIT] animate or inanimate (i.e. equal or lower rank)
- S is always unflagged.
So we have two explicit
case markers used for terms,
-e for the
ergative case when A is flagged and
-ad for the
accusative case when P is flagged. Then we have the unmarked form seen in all terms under certain circumstances. For now I've chosen to analyze A/P as syntactically conditioned allomorphs of the ergative and accusative cases, respectively, leaving an additional case, the direct case, for S (which just happens to be syncretic with those unflagged forms).
A
dative case marker
-za is available to sentient and animate referents serving as IO. Inanimate referents cannot serve as IO and do not have this form. In causatives of transitive verbs, where the non-causative A is typically demoted to IO, an inanimate referent must instead become an adjunct, sometimes in the ablative, sometimes involving
mbrambe 'because of', see later. The dative is also used to mark X when the benefactive applicative voice is marked on the verb; when X is inanimate, use the accusative marker
-ad instead (but in this case, we call it the allative case). X controlled by the other two applicatives are simply accusative, subject to the same deflagging if inanimate as P.
So those are our
argument cases: direct, ergative, accusative and dative.
Then there's a single
adnominal case, the
genitive. This one doesn't have a marker of its own so it borrows from others. On sentient/inanimate possessees, that is the dative marker
-za. On inanimates, again it's the
-ad, but one that doesn't go away. If the possessor is inanimate, flagging the genitive becomes optional, so you can say simply
hadāl ḫuḫahum 'the roof of the house' instead of the fully expressed
hadālad ḫuḫahum.
Lastly, there are four
adverbial cases. In general, sentient nouns are resistant to these and need the supportive morph
-na before the case marker. This is the same as the anaphoric pronoun
na.
The
allative is marginal; only inanimate referents can take
-ad for allative. Animate nouns can take the locative
-ka/ak in the same conditions. Sentient referents on the other hand, have to be couched in inanimate nouns, such as
dikejar 'direction' or a body-part noun. It means something like 'to', 'toward' or 'into'.
The
locative has
-ka or
-ak (the latter if the preceding segment is a stop). It means something like 'at', 'in' or 'on'.
Both the locative and allative are unflagged for proper nouns of place, e.g.
Kādar inep 'I went to Kadar', not *
Kādarad inep.
The
ablative has
-ube. It means something like 'from', 'out of' or 'off'.
The
instrumental has
-amma and means something like 'with', 'using', 'by' or 'in an X way'.
The case markers (
-e, -ad, -za, -ak/ka, -ube, -amma) are phrase-final clitics and attach to the final word of the NP. However, they behave as affixes in that they are subject to hiatus collapse and they affect stress. While the final word is usually the noun, it can also be a relative clause or a number of other dislocated modifiers. Sentient nouns with the supportive
-na take
-na directly, so it may be detached from the case marker if something is moved after the noun within the NP.
In addition to case markers, there are a handful of words best termed
postpositions phonologically and prosodically behave as separate words. The most postposition-like words are
da and
dabu, 'with' and 'without', which take an object in the accusative (unflagged if inanimate). Unlike -
za, for instance, they don't pull stress. Whereas
mamanza 'to father' is stressed on the final syllable
mamanzá wheras
mamanád da 'with father'. So the combination of the presence of the accusative marker and the difference in stress behavior shows these are slightly different than the case markers.
Then there's the word
mbrambe 'because of' which needs a dative with sentient/animate referents, but no marker if inanimate. It's clearly related to a noun
ḫambran 'reason' in an abbreviated ablative case form. The abbreviated ablative ending
-be and the missing referential index
ḫa- are associated with satellites (more on those later). But unlike satellites, which stand in apposition with same-case phrases rather than controlling their case per se,
mbrambe seems to be triggering genitive agreement – but to complicate matters, it drops the ending with inanimates (which does not happen with typical genitives), perhaps in analogy with the behavior seen with
da/dabu. So the simplest thing is to treat
mbrambe as another postposition.
So to summarize, there are nine syntactic cases (direct, ergative, accusative, dative, genitive, allative, locative, ablative, instrumental), six morphological case markers, and at least three postpositions. Core case markers are not expressed in ideal argument situations, locative/allative is not expressed with proper nouns of place, inanimate objects of postpositions are unflagged and genitives may go unexpressed with inanimates. Together these non-expressions of case are called
the rules of parsimonious case marking because they are all semantically motivated and aligned with statistically common and likely uses.
