====== Sirva ======

Timothy Usher, Santa Fe Institute

===== Situation =====
Sirva, known also as Sileibi, is spoken by perhaps 259 people (1975) living in four villages, Kamambu, Kumbuna, Musita and Sileibi, from the confluence of the Savai and Sogeram rivers in the west to the upper Gogol River in the east in the Middle Ramu district of Papua New Guinea's Madang province. Sirva /siɾβa/ is the name that speakers call their language; its meaning is unknown. Sileibi is the name of a Sirva-speaking village (Z'graggen 1975: 29, Daniels 2015: 658.)

===== Kin terms =====
Inalienable possessors of kin terms are indicated by prefixes, by suppletion or both (Daniels 2015: 675-677.) These prefixes are undifferentiated by number. The first person possessor may be indicated by /a-/, /ja-/ or zero, the first of these being archaic. Examples unclude:

|< - 100px 100px 100px 100px 100px >|
|           |root         |1 sg./pl.|2 sg./pl.|3 sg./pl.|
|           |             |**a-**   |**na-**  |**nɨ-**  |
|sister     |ɾɨma         |a-ɾɨma   |na-ɾɨma  |nɨ-ɾɨma  |
|           |             |**ja-**  |**na-**  |**n-**   |
|father     |βa ~ wa/ŋindi|ja-βa    |na-ŋindi |n-ua     |
|           |             |**Ø-**   |**na-**  |**n-**   |
|son-in-law |inum         |Ø-inum   |na-num   |n-inum   |
|grandfather|tata/sɨⁱ     |Ø-tata   |na-sɨⁱ   |nɨ-sɨⁱ   |
|           |             |**?**    |**na-**  |**nu-**  |
|son        |ɣus          |[ja-ŋ ɲa]|na-ɣus   |nu-ɣus   |

(The first person singular form of "son" /ja-ŋ ɲa/ means merely "my son"; q.v. /ja-ŋ/ 1 sg. possessive above.)\\
\\

Kin terms may be marked for plural by the addition of one of a number of suffixes, /-nin/, /-ɲa/ or /-ɣaɾ -ŋgaɾ -nzaɾ/ the choice of which is lexically specified.



===== Verbal morphology =====
Daniels (2015: 704-725) gives subject desinences for Sirva indicative final verbs in five tense paradigms as follows, with habitual and future tenses marked by additions to the today past:

|< - 100px 100px 100px 100px 100px 100px >|
|      |today past|habitual     |future       |yesterday past|far past|
|1 sg. |-ɾi-n     |-ɾaβa-ɾi-n   |-βanan-di-n  |-ma-n         |-sɨ-n   |
|2 sg. |-ɾi-na    |-ɾaβa-ɾi-na  |-βanan-di-na |-ma-na        |-sɨ-na  |
|3 sg. |-ɾi-Ø     |-ɾaβa-ɾi-Ø   |-βanan-di-Ø  |-m-Ø          |-s-a    |
|1 pl. |-ɾi-ɾ     |-ɾaβa-ɾi-ɾ   |-βanan-di-ɾ  |-ma-ɾ         |-sɨ-ɾ   |
|-2 pl.|-ɾi-ɾa    |-ɾaβa-ɾi-ɾa  |-βanan-di-ɾa |-ma-ɾa        |-sɨ-ɾa  |
|3 pl. |-mb-ɾi-Ø  |-ɾaβa-mb-ɾi-Ø|-βana-mb-ɾi-Ø|-mbɨ-m-Ø      |-mbɨ-s-a|

The constituents of these desinences are as follows:

|< - 100px 100px >|
|          |subject   |
|today past|-n        |
|2 sg.     |-na       |
|3 sg.     |-Ø        |
|1 pl.     |-ɾ        |
|-2 pl.    |--ɾa      |
|3 pl.     |-mb(ɨ)-…-Ø|


|< - 100px 100px >|
|              |tense      |
|today past    |-ɾi- ~ -di-|
|yesterday past|-m(a)-     |
|far past      |-s(ɨ)-     |

Irrealis or imperative verbs take an entirely different set of subject suffixes:

|< - 100px 100px >|
|      |imperative|
|1 sg. |-ɨnda     |
|2 sg. |-u        |
|3 sg. |---       |
|1 pl. |-ɨndaŋgɾa |
|-2 pl.|-uɣɾa     |
|3 pl. |-mb-andi  |
|1 dl. |-ɨndaŋ    |

Medial verbs are distinguished according to whether their subjects are the same as or different from the subject of the final verb. The symbol <C>:in different subject simultanous forms symbolizes a segment redplicated from the root:

|< - 100px 100px 100px 100px 100px >|
|      |different subject|different subject|same subject|same subject|
|      |sequential       |simultaneous     |unmarked    |desiderative|
|1 sg. |-ɨⁱ-n            |-ɨⁱ-n-C-ɨⁱ-n     |-a ~ -ɾa    |-βana       |
|2 sg. |-ɣa-na           |-ɣa-na-na        |-a ~ -ɾa    |-βana       |
|3 sg. |-ɨⁱ              |-ɨⁱ-C-ɨⁱ         |-a ~ -ɾa    |-βana       |
|1 pl. |-ɣa-ɾ            |-ɣa-ɾ-ɣa-ɾ       |-a ~ -ɾa    |-βana       |
|-2 pl.|-ɣa-ɾa           |-ɣa-ɾa-ɾa        |-a ~ -ɾa    |-βana       |
|3 pl. |-mb-ɨⁱ           |-mb-ɨⁱ-mb-ɨⁱ     |-a ~ -ɾa    |-βana       |

While the desiderative is usually medial, it can also function as a final verb in some contexts. It may be seen that /-βana/ is the same root as the future tense marker /-βanaN-/ above with regular loss of word-final nasal.\\
