Nawa River

Timothy Usher, Santa Fe Institute

Situation

The Nawa River family consists of two languages, Kaure and Kosare, spoken to either side of the upper Taritatu (Idenburg) river, mostly west of the Nawa and Sobger rivers, in the hill country east of the Lakes Plains in the Airu and Kaureh districts of the Jayapura regency in Indonesiaˈs Papua province (Voorhoeve 1975: 422-423, Wurm 1982: 197, Dommel and Dommel 1991: 2, Dommel 1992: 89-91, Wambaliau 2006: 2-4, q.v. Menanti and Rumaropen 2009: 3.)

Subclassification

The internal classification of Nawa River is as follows:

Nawa River

Kaure

Kosare

Voorhoeve (1975: 45, Smits and Voorhoeve 1994: 9-10) identifies a third language, Narau, following the vocabularies of the Anceaux collection in which smatterings of Narau forms, said to have been collected in the Lakes Plains region, are excerpted from Giël (1959.) Narau is the name of a river which is nowadays seasonally occupied by Kapauri and Kosare people from Pagai and Naira villages respectively (Wambaliau 2006: 2;) the Kaure call this group Mbalu /mbaɺu/ (Dommel, Dommel, Auri and Pokoko 1991: 84.) While there are not enough terms in Anceauxˈs excerpts to arrive at a definitive conclusion, there is little in the vocabulary to suggest that Giëlˈs Narau is anything but a variety of Kaure, with Dommel and Dommel (1991: 2) stating that the two are mutually intelligble.

History of classification

Voorhoeve (1971: 51, 77-78,) working from Galisˈ (1956) vocabulary, lists Kaure as an unclassified language having no evident historical relationship to any of its known neighbors. Soon thereafter he gained access to Anceauxˈs collection of vocabularies and by (1975a: 45) placed the Kaure Family, consisting of Kaure and Narau (see comments on Narau above,) in a Kaure Stock alongside Kapori (Kapauri) and Sause, the Kosare language having not appeared in the literature until Heeschen (1978.) This was further asserted to constitute a Subphylum-level Stock within the much larger Trans-New Guinea Phylum (1975b: 422-423.) No arguments were presented in support of this proposal save for what is visible in the accompanying 40-term wordlists (1975a: 114-115.)

Wurm (1982: 197) expanded Voorhoeveˈs Kaure Family to include the recently-attested Kosare as coequal to Kaure and Narau, otherwise maintaining Voorhoeveˈs classification unchanged, and characterized the degree of relationship between the three as “on the lower medium to high family level” in contrast to the “low stock level” relationship uniting the Kaure Family, Kapori and Sause.

Hammarström (2010: 188, reiterated in Pawley and Hammarström (2017: 81) … “Voorhoeve (1975b) grouped Kapauri with the Kaure languages based on some lexical correspondences. However, a newer evaluation of the lexical relationships reveals figures that are only in the range of 5–6%, shedding considerable doubt on a geneticrelation between the Kaure languages and Kapauri (Rumaropen 2006:13).”

Foley (2017: …) …

We find that Kaure and Kosare form one group, designated here as Nawa River, and Kapauri and Sause another which is related most closely to Masep, Isirawa and Apauwar River (i.e. Kwerba) and has no special relationship to Nawa River. This fundamental division is supported by Dommel and Dommel (1999: 1-2,) who counted only 1% lexical similarity between Kaure and Sause of Badrun village, and by Wambaliau (2006: 12-13) and Menanti and Rumaropen (2009: 13-14,) who found only 5-6% lexical similarity between Kosare and Kapauri village, most of which can be attributed to loans (below.) Unfortunately, none of the SIL researchers are known to have compared Kaure with Kosare or Kapauri with Sause, but a fair accounting of the resemblances within each of these two pairs would yield a much higher figure, as demonstrated in the sections which follow.

Historical phonology

[under construction]

Proto-Nawa River had 11 or 12 consonants and perhaps 8 vowels as follows:

*m *n
*p *t *k
*b *g
*s *h
*w [*j]
*i *u
*e̝ *o̝
*a

In addition to the simple vowels given above, at least four diphthongs are found as follows:

*ɛⁱ *ɛᵘ
*aⁱ *aᵘ

Voiced stops /*b *g/ have not been found to occur intially. Unoccluded voiceless fricative /*h/ has not been found to occur medially. This assymetry suggests that one or more pre-Kaure initial voiceless stops became /*h/, while initial voiced stops were devoiced.

There is no apical voiced stop /*d/, suggesting non-stop /*ɽ/ to be its systemic equivalent; this is the case also in the neighboring Kapauri-Sause family. Initial /*ɽ/ is very uncommon, in keeping with the absence of initial voiced stops /*b *g/; presumably this pre-Kaure /*d/ would be reflected as initial voiceless /*t/.

Supporting these notions is the fact that the Orya language immediately to the north, along with Orya-Tor River more generally, has undergone the same changes from proto-West North New Guinea; for example bilabial voiced prenasalized /*mb/ is devoiced to /*p/ in Orya-Tor River and then deoccluded to /h/ in Orya, with apical /*nd/ likewise becoming Orya-Tor /*t/.

Only two archiphonemic consonants are distinguished finally, nasal /*N/ and stop /*C/:

*N
*C

Dommel and Dommel (1991: 7-15) describe a tonal distinction in Kaure which must be reconstructed for the Nawa River level as well, as it is plainly contrastive and not reducible to any segmental changes within the family. These are given by Dommel and Dommel as high tone and high-mid falling tone, but can be viewed systemically as high tone against low tone, the former being significantly more common. Unfortunately, this distinction is not indicated in Wambaliauˈs Kosare or in Dommel, Dommel, Auri and Pokoko (1991) or Auri, Dommel and Pokoko (1991,) only in Dommel and Dommelˈs (1991) phonology, which discusses only a selection of attested roots and even so is not entirely consistent in this respect.

Initial consonants and consonant clusters correspond as follows:

Nawa River Kaure Kosare Kosare
Dommel Heeschen Wambaliau
*m-/_(C) mb b m
*m-/_N m m m
*n-/_C nd n d n d
*n-/_(N) n n n
*p- p p p
*t- t t t
*k- k k k
*s- s s s
*h- h ø ø
*w- w w w
*ɽ- ɺ ɽ
*j-

Medial consonants and consonant clusters correspond as follows:

Nawa River Kaure Kosare Kosare
Dommel Heeschen Wambaliau
*-m- m m m
*-n- ɺ n
*-p- p p p
*-t- t t t
*-k- k k k
*-b- p b b
*-g- k ? g
*-s- s s s
*-w- w w w
*-ɽ- ɺ ɽ
*-j-

Final consonants correspond as follows:

Nawa River Kaure Kosare Kosare
Dommel Heeschen Wambaliau
*-N ø
*-C ʔ ø

Vowels and diphthongs correspond as follows:

Nawa River Kaure Kosare Kosare
Dommel Heeschen Wambaliau
*i i i i
*u ʉ u u
*e̝ ɛ e e i
*o̝ o u
ɛ e ɛ
*ɛ/_Cu e u u
o o
a ɛ ɛ
*a a a a
*ɛⁱ ɛⁱ i
*aⁱ aⁱ i
*ɛᵘ ɛᶶ u
*aᵘ aᵒ aᵘ

These correspondences are examplified as follows, with Kaure attestations drawn from Dommel, Dommel, Auri and Pokoko (1991, Dommel and Dommel 1991,) Kosare from Heeschen (1978: 41-44) and Kosare of Muara Nawa and Naira villages from Wambaliau (2006: 24-30.)

Kaure stress and tone are indicated only where they are known from Dommel and Dommelˈs (1991) phonology; where their tone assignations are inconsistent, both versions are given. A more vexsome problem is the indication of front mid vowels, as Dommel and Dommel ditinguish high mid /e/from low mid /ɛ/, but this is not indicated in their practical orthography. This distinction is not correlated with that between Nawa River /*e̝/ vs. /*ɛ/, so comparison to Kosare is of no use. However, Dommel and Dommel's high mid /e/ is uncommon, and is found only root-finally (pp. 41, 63-65.) Diphthong /ɛⁱ/ is realized as [e] in some contexts, where it is likewise written as <e> in the dictionary, leading to further questions. We have specified /ɛⁱ/ where it is given in the phonology, but otherwise can do little to address the overall problem other than to state that the effect upon the veracity of the reconstruction presented here is necessarily limited. Where the phonology specifically indicates either /ɛ/ or /e/, we present these as <ɛ e̝> respectively, leaving unmarked <e> to symbolize attestations found only in the dictionary, where its value cannot be determined.


Any consonant except for voiced stops /*b *g/ can occur initially, though initial apical non-stop /*ɺ/ is only very thinly attested.

Initial bilabial nasal /*m/, unless followed by a nasal consonant (below,) is reflected as voiced prenasalized stop /mb/ in Kaure. According to Dommel and Dommel (1991: 31,) in some words this is in free varation with [m]. One example in Heeschenˈs Kosare gives voiced stop [b]:

Nawa River Kaure Kosare Kosare Kosare
Dommel Heeschen Muara NawaNaira
*m-/_V(C)mb [mb m]b m m m
water *mi[jɛ] mbí biɛ ~ miɛ-ˈmijɛ ˈmijɛ

guts *m[e̝/ɛ]pæ -mbepa -mɛˈpɛʔ ˈmiˈpɛʔ
house *ma mbá ma ma
wallaby*maja mbaja maˈjaʔ

When followed by a nasal consonant in the next syllable or a nasalized vowel reflecting final nasal archiphoneme /*N/ (below,) initial /*m/ is retained as such in Kaure:

Nawa River Kaure Kosare Kosare Kosare
DommelHeeschenMuara NawaNaira
*m-/_VNm m m m
louse *miN mi miʔ miʔ
drink *mɛN mɛ̃́
breast *muN mʉ̃̂ ˈmu ˈmu
drink (sg.)*mnɛN -mɺẽ -ˈmɛnɛ mnɛ mnɛ

Initial apical nasal /*n/ … According to Dommel and Dommel (1991: 32-33,) in some words this is in free varation with [n]. One example in Heeschen and one in Wambaliauˈs Kosare of Muara Nawa give voiced stop [d]:

Nawa River Kaure Kosare Kosare Kosare
Dommel HeeschenMuara NawaNaira
*n-/_VCnd n d n d n
rain *nɛⁱC ndɛ́ⁱʔ ~ ndɛ̂ⁱʔ di ni
sky *nɛbu ndéˈpʉ́ nubʊ ⁿuˈbuʔ ⁿuˈbuʔ

… /*n/ …:

Dommel HeeschenMuara Nawa Naira
*n-/_V# n nd n n n nd

1 sg. poss.*na- ná- ~ ndá- na na- na-
*n-/_V(N)n n n
cry out *nɛɽæN néɺã́ -nɛˈɭɛʔ -nɛˈɭɛʔ

In one example, initial /*n/ is dropped entirely in Kosare with consequent nasalization of the following vowel; this should probably be viewed as a further development of the reflex given as [ⁿ] (above):

Nawa RiverKaure Kosare Kosare Kosare
DommelHeeschenMuara NawaNaira
*nV[N]nV
excrement*na[N] na; nãã ãʔ ~ a- ãʔ

… /*n/ … It may be seen in Dommel, Dommel, Auri and Pokokoˈs (1991: 140-143) vocabulary that kin terms are disproportionately represented among Kaure words beginning with [n]. This is likely because kin terms are obligatorily possessed, either by an inalienable prefix or by a personl name, and both first and third person inalienables begin with /n/ (Dommel 1992: 94) … :

ear *hwɔkɽuC ˈhókɛ́ɺʉ́ʔˈkɔro wɔˈɽuʔ wɔˈɽuʔ

In one example, initial /*h/ is unexpectedly retained as such in Kosare, perhaps indicating a doublet from Kaure:

Nawa RiverKaure Kosare Kosare Kosare
DommelHeeschenMuara NawaNaira
*h- h ø h h h
bird*ho̝C hôʔ o ~ ho- hu huʔ

Another may be a loan from Kaure or from some third source:

Nawa RiverKaure Kosare Kosare Kosare
DommelHeeschenMuara NawaNaira
*h- h h
fear*ho̝ hʊ̃

Another seeming exeption is a loan from Sause (below,) in which /h/ is the regular reflex of Kapauri-Sause /*s/:

Sause Kaure Kosare Kosare Kosare

h-h h

Initial bilabial non-stop /*w/ is retained as such in both Kaure and Kosare:

*w- w w w w
1 pl. excl.*wɛN wɛ̃́ wɛ-nɛ wɛ-ˈnɛ wɛ-ˈnɛ

Initial apical non-stop /*ɽ/ has been found in only one root, where it is realized as lateral flap /ɺ/ in Kaure just as are medial and final /ɽ/ (below):

Nawa RiverKaure Kosare Kosare Kosare
DommelHeeschenMuara NawaNaira
*ɽ- ɺ ɽ ɽ
hole*ɽo̝C ɺoʔ ru- ˈɽu-

The only known example of initial palatal non-stop /*j/ is a widespread northwest New Guinea regional term (below) and probably a loan into the Nawa River languages:

Nawa RiverKaure Kosare Kosare Kosare
Dommel HeeschenMuara NawaNaira
*j- ø
sago porridge*je̝saⁱ ésjáⁱ ~ ísjáⁱ dʒiˈsi

Any consonant except unoccluded voiceless fricative /*h/ can occur medially.

Medial bilabial nasal /*m/, unlike initial /*m/ (above,) is retained as such in Kaure as well as Kosare regardless of whether the following vowel is nasalized:

Nawa RiverKaure Kosare Kosare Kosare
DommelHeeschenMuara NawaNaira
*-m- m m m m
knee *a[ji]mo̝Namõ aimó aiˈmuʔ aiˈmuʔ
knife*to̝m[w]a tomwa ˈtuma ˈtuma
leech*hame̝ hame ˈaˈmi ˈaˈmi

Medial apical nasal /*n/ is merged with the reflex of apical non-stop /*ɽ/ [ɺ] in Kaure, regardless of whether the following vowel is nasalized:

Nawa RiverKaure Kosare Kosare Kosare
DommelHeeschenMuara NawaNaira
*-n- ɺ n n n
drink (sg.)*mnɛN -mɺẽ -ˈmɛnɛ mnɛ mnɛ

Where word-medial apical /*n/ is the first consonant of a root in a compound, it is retained as such in Kaure:

*-n- n n n n

Medial bilabial voiceless stop /*p/ is retained as such in both Kaure and Kosare:

husband *no̝ko̝ɽsaⁱnokosaⁱ ˈnukuɽeˈsiʔˈnukuɽeˈsiʔ

In at least two examples, Kaure medial /k/ corresponds to zero in Wambaliauˈs Kosare. The Kaure word given as /ɺóˈkó/ “hole” is found also as /ɺoʔ/ “ravine, gorge” (Dommel, Dommel, Auri and Pokoko 1991: 138) suggesting the intervening vowel below to have been interpolated. In support of this notion, Dommel and Dommel (1991: 19) state that /k/ never occurs syllable-finally. We interpret the correspondences in both of these instances as those of medial cluster /*kC/:

Nawa RiverKaure Kosare Kosare Kosare

The second of these contrasts directly with /*po̝k[o̝]ɽɛ/ “salt” above, in which both consonants are preserved in Kosare, indicating the presence of an underlying vowel between them.

Medial laminal voiceless fricative /*s/ is retained as such in both Kaure and Kosare:

sago porridge*je̝saⁱ ésjáⁱ ~ ísjáⁱ dʒiˈsi

Unoccluded voiceless fricative /*h/ has not been found to occur root-medially, although it does synchronically in Kaure.

Medial bilabial voiced stop /*b/ is devoiced and merged with the reflex of voiceless /*p/ in Kaure:

Medial velar voiced stop /*g/ is uncommon. It is devoiced and merged with the reflex of voiceless /*k/ in Kaure:

Nawa RiverKaure Kosare Kosare Kosare
Dommel HeeschenMuara NawaNaira
*-g- k g g
coconut*sɛgu sɛ́ˈkʉ̂ ˈsugu- ˈsugu-

One example in which the term for “mouth” (cf. Kaure /sɛ-ɺóˈkó/, literally “chin-hole”) has been suffixed with /*ki/ “skin” to yield the meaning “lip(s)” suggests /*ki/ to be underlyingly /*gi/, with voiced /g/ surfacing as such only in medial position:

Final stop archiphoneme /*C/ is realized as glottal stop /ʔ/ in Kaure. It is not clear that sporadic glottal stop in Kosare is meaningful as it is found also following final vowels and final /*N/ (above):

Among the vowels and diphthongs, only low central /*a/ occurs initially, and even so only in a few roots, two of which are kin terms. Thus, very few Nawa River roots are vowel-initial. Any vowel can occur medially or finally.

High front vowel /*i/ is retained as such in both Kaure and Kosare:

High mid back rounded vowel /*o̝/, variably realized as [o u ɤ ɯ] in Kaure (Dommel and Dommel 1991: 42-44,) is raised and merged with the reflex of high back /*u/ in Wambaliauˈs Kosare but not in Heeschenˈs:

When high mid-back /*o̝/ is followed by a front vowel or diphthong /*ɛ *ɛⁱ/ in the next syllable, it is reflected as [wi] in Kosare:

A smaller number of words can probably be identified as loans from Kapauri-Sause into Kaure and/or Kosare. In the case of “long,” this is mandatory on phonological grounds as Nawa River initial /*h/ is dropped in Kosare (above):

Kapauri-SauseKapauri Sause Kaure Kosare Kosare

blunt/dull*ho̝t[u]C hutʊ hutuk [Ures]hotɛᵘʔ

One Kapauri-Sause word which looks very similar to the Nawa River form and would likely have been included in Wambaliauˈs (2006: 12-13) and Menanti and Rumaropenˈs (2009: 13-14) lexical similarity figures is conceivably a legitimate retention from proto-Foja Range; cf. Grime River /*min/:

Nawa RiverKapauri-SauseKapauriSause
breast*muN *mɵ̝N my meːŋ

In a number of words thusfar found only in Kapauri and Kaure, the direction of borrowing cannot be determined upon distributional grounds:

Kapauri Kaure
skin/barkufunʉ ~ uvunyáhóˈɺîʔ
mother ani ande
old aiba-ɽu adʒepa ~ aipa
one kakʷitija kákódʒã̂ ~
kakotẽn

The Kaure words above include several marginal sounds, namely medial /h/, which has no known Nawa River origin, medial /nd/ and laminal voiced affricate /dʒ/. Kaure /áhóˈɺîʔ/ “skin/bark” appears to have replaced Nawa River /*ki/ (above) which is now given as “rind, pod, peel” (Dommel, Dommel, Auri and Pokoko 1991: 135) or “shell” (Dommel and Dommel 1991: 10.)

There are also a number of words which have been found only in Kapauri and Kosare:

Kapauri Kosare Kosare
Muara NawaNaira
tired aitehɛnɪ aitahiˈni ˈaitahini
kunai grassufanija paˈjãʔ
paddle təjka ~ təikatɛiˈka tɛiˈka
goanna tamakɪja tamaˈkia tamakia
taro saku soˈkuʔ soˈkuʔ
leaf/hair su; ɪsuʔ uˈsuʔ suʔ; uˈsuʔ
stone/sand ɭitɪ liti- liti-

The Kosare term for “leaf” is likely a loan from Kapauri, where /su/ is given as “hair” (cf. /*haⁱ/ above;) Naira [suʔ] is given as “roof.” The term for “paddle” is found alongside the reflex of the native term /*tɽo̝wa/ (above.) The term for “kunai grass” is phonologically easier to explain as a loan from Kapauri into Kosare than vice-versa, as is that for “tired,” where there is no known native source for Kosare medial /h/. It seems then probable that most to all of the words listed above are loans from Kapauri into Kosare, which makes a good deal of sense in light of the recent history of Kosare resettlement as described by Wambaliau (2006: 4.)

… Sause and Kaure … The word for “black cockatoo” is found also in Anceaux's Orya of Sigi village as [bargwe] (Smits and Voorhoeve 1994: 249) and probably originates with Kaure since otherwise there is no origin for final nasalization:

Kaure Sause
bush fowl mbahapemahaβɛ [JA]
black cockatoomaɺokwĩmbargwe [JA]
mouse/rat kɛɺsi kɭisjə
fat/grease kʷaⁱsoagʷaⁱtʃa [PD]
egg/seed ɺɛ̃̂ ɭeŋ

Deapite Schiefenhövelˈs (1978: 49) assertion that the Kosare take Sirkai (Ketengban) wives, there is little lexical influence from the Mek family, which is allied first to Momuna and then to the Digul River-Ok languages to the south of the cordillera:

Mek Kosare Kosare Kosare
HeeschenMuara NawaNaira
hot*bɔᵘbʊpɔˈbu poˈpu poˈpu

Another example would seem to be a loan from Kaure into Mek, as while the prefixation of [se- s-] (from /*se̝N/) upon words for mouth-related terms is typical of both Kaure and Kosare, there is no such prefix in Mek, where the initial variation would be irregular (Ketegban from Sims, Sims, Basini, Difur and Uropka 1990: 22, Yale Kosarek from Heeschen 1992: 136):

Kaure KetengbanYale Kosarek

… regional … Kaure's two terms for “tobacco” are doublets, Anceaux's [sambuãŋ] (Smits and Voorhoeve 1994: 105-106) coming directly from Orya [sabwan]:
