Numbami (also known asSiboma orSipoma) is anAustronesian language spoken by about 200 people with ties to a single village inMorobe Province,Papua New Guinea. It is spoken in Siboma village (7°30′47″S147°18′04″E / 7.512985°S 147.301128°E /-7.512985; 147.301128 (Siboma)), Paiawa ward,Morobe Rural LLG.^[2][3][4]

Numbami is a phonologically conservative isolate within theHuon Gulf languages, and is the last Austronesian language on the south coast of theHuon Gulf. Its nearest relatives along the coast to the southeast are 270 km away,Maisin andArifama-Miniafia inOro Province (Northern Province in the former colony of Papua).

Theword order typology of Numbami and the Huon Gulf languages issubject–verb–object (SVO), which is typical of Austronesian languages; while that of Arifama-Miniafia and most of thePapuan Tip languages issubject–object–verb (SOV), which is typical ofPapuan languages. Maisin has been characterized as amixed language, with both Austronesian and Papuan features that obscure its primary heritage, and there is evidence that settlements of Austronesian speakers along the 270 km of coast were gradually absorbed into inland communities speakingBinanderean languages (Bradshaw 2017).

Numbami distinguishes 5 vowels and 18 consonants. Voiceless /s/ is a fricative, but its voiced and prenasalized equivalents are affricated, varying between more alveolar[(n)dz] and more palatalized[(n)dʒ]. The liquid /l/ is usually rendered as a flap[ɾ]. The labial approximant is slightly fricative, tending toward[β], when followed by front vowels.

Prenasalized obstruents only occur in medial position, where the distinction between oral and prenasalized voiced obstruents is somewhat predictable. Medial voiced obstruents are statistically far more likely to be oral in words beginning with oral voiced obstruents, while they are far more likely to be prenasalized in words beginning with anything else. If denasalization of voiced obstruents is an ongoing change, one can track its progress through different lexical environments: it is 100% complete in word-initial position (as inbola 'pig' andbuwa 'areca nut'), 80% complete in the middle of words beginning with voiced obstruents (as inbada 'market' anddabola 'head' vs.zanzami 'driftwood'), 35% complete in the middle of words beginning with approximants or vowels (as inababa 'crosswise' vs.ambamba 'handdrum' andwaŋga 'canoe'), not quite 20% complete in words beginning with voiceless obstruents (as inkaze 'left side' vs.kaimbombo 'butterfly' andpindipanda 'flea'), not quite 5% complete in words beginning with nasals (as innomba 'thing' and-mande 'to die'), and not attested at all in words beginning with liquids (as inlenda 'nit' andlindami 'lime spatula'). (See Bradshaw 1978a.)

Although Numbami is phonologically conservative, it retains very little productive morphology, most of it related to person and number marking.

Free pronouns occur in the same positions as subject or object nouns. They distinguish three persons (with aclusivity distinction in the first person) and four numbers (Bradshaw 1982a).

Genitive pronouns also distinguish three persons (plusclusivity) and four numbers (Bradshaw 1982a).

Verbs are marked with subject prefixes that distinguish three persons (plusclusivity) and two tenses, Nonfuture and Future. (The latter distinction is often characterized as one between Realis and Irrealis mode; see Bradshaw 1993, 1999.)

In most cases, subject prefixes are easily segmentable from verb stems, but in a few very high frequency cases, prefix-final vowels merge with verb-initial vowels to yield irregularly inflected forms, as in the following paradigm:wani (<wa-ani) '1SG-eat',woni (<u-ani) '2SG-eat',weni (<i-ani) '3SG-eat',tani (<ta-ani) '1PLINCL-eat',mani (<ma-ani) '1PLEXCL-eat',moni (<mu-ani) '2PL-eat',teni (<ti-ani) '3PL-eat'.

Traditional Numbami counting practices started with the digits of the left hand, then continued on the right hand and then the feet, to reach '20', which translates as 'one person'. Higher numbers are multiples of 'one person'. Nowadays, most counting above '5' is done in Tok Pisin. As in otherHuon Gulf languages, the short form of the numeral 'one' functions as an indefinite article.

Like many otherHuon Gulf languages, Numbami has a system of birth-order names. The seventh son and sixth daughter are called "No Name": Ase Mou 'name none'.

Although many languages have a class ofideophones with distinctive phonology, Numbami is unusual in having a morphological marker for such a class. The suffix-a(n)dala is unique to ideophones but is clearly related to the wordandalowa 'path, way, road' (POc *jalan). (See Bradshaw 2006.) In the following examples, acute accents show the placement of word stress.

• bái-andala 'overcast, clouded over'
• dendende-ándala 'shivering'
• golópu-adala 'slipping or dripping through'
• kí-andala 'scorching, parched'
• paká-adala 'getting light, flashing on, popping'
• pilipíli-adala 'flapping, fluttering'
• sí-andala 'shooting up, springing away'
• sulúku-adala 'sucking, slurping'
• taká-adala 'stuck fast, planted firmly'
• tíki-adala 'going dark'

The basicword order in Numbami is SVO, with prepositions, preposed genitives, postposed adjectives and relative clauses.Relative clauses are marked at both ends, and so are someprepositional phrases. Negatives come at the ends of the clauses they negate. There is also a class of deverbal resultatives that follow the main verb (and its object, if any).

Two kinds of genitive modifiers precede their heads while one type follows its head noun (Bradshaw 1982a).

Noun-noun phrases denoting wholes and parts occur in the order stated, with the latter serving as head of the phrase:wuwu lau 'betel pepper leaf',tina daba 'headwater',nima daba (lit. 'hand head') 'thumb',kapala lalo (lit. 'house inside') 'indoors',Buzina bubusu 'Buzina (Salamaua) point'.

Genitive possessor nouns precede their head nouns, with an intervening possessive marker that distinguishes singular (na) from plural (ndi) possessors:wuwu na lau 'the leaves of the (generic) betel pepper plant; particular betel pepper plant's leaf';kapala na lalo 'the insides of (generic) houses; the inside of a particular house';Siasi ndi gutu 'the Siassi Islands; islands belonging to a particular group of Siassi people';bumewe ndi bani 'food typically eaten by whites; food belonging to a particular group of whites'.

Attributive genitives resemble possessive genitives except that (1) the modifiers follow their heads, and (2) the "possessors" are nonreferential except in a generic sense, that is, they "never refer to a particular subset of the set they name" (Bradshaw 1982a:128):wuwu weni na 'forest (wild) betel pepper',wuwu Buzina ndi 'type of betel pepper associated with the Buzina people at Salamaua',walabeŋa tamtamoŋa na 'fish poison, native means of stunning fish',walabeŋa bumewe na 'explosives, European means of stunning fish'.

Verb serialization is very common in Numbami. Within a serial verb construction, all verbs must agree intense.Subject choice in successive verbs is severely constrained. Noninitial subjects can only refer to preceding subjects, preceding objects, or preceding events or conditions, and only in that order (Bradshaw 1993). Negatives come at the ends of the clauses they negate.
