Proto-Koyanic language

Proto-Koyanic (PKn), also known as Proto-Arklobu-Qachkav (PAQ), is the reconstructed common ancestor of the Koyanic languages, a language family found throughout the Koyan region of western Fountainhead. Proto-Koyanic was likely spoken as a singular language in Kóty c. 4,000 - 3,000 BGS before breaking up into its major branches via major migrations through the third and second millennia BGS.

Consonants
The reconstructed consonant inventory of Proto-Koyanic is presented below.

Sibilants
The sibilants *z *s pattern very similarly to the plain-aspirated plosive pairs, leading to some suggesting affricate qualities [ts tsʰ] or even palatalised plosives [tʲ tʲʰ]. Nonetheless, the reflexes of these consonants in descendent languages strongly support their reconstruction as a voiced-voiceless pair of fricatives [z s], in particular the frequent rhotacisation of *z to [r] and debuccalisation of *s to [h].

It is quite possible that these consonants developed from older plosives which shifted to fricative qualities, a change which notably occurred again in Proto-Gäj which lost original PKn *z *s, then shifted *c *cʰ to *z *s which continue to pattern like plosives.

Palatals
The palatal plosives *c and *cʰ are reflected by Proto-Duodoseic *k, indicating that Duodoseic may have branched at an early stage of the language which instead had palatalised velar stops *kʲ *kʲʰ, while the rest of the language family strongly supports the reconstruction of true palatals. By convention, these consonants are transcribed *c *cʰ even in considering Proto-Koyanic as the common ancestor of the entire family including Duodoseic.

Laryngeals
* ʡ and *h likely had the same place of articulation and formed a plain-aspirated pair like the plosives. Whether these were pharyngeal [ʡ ħ] or glottal [ʔ h] is not known, but the Duodoseic reflection of *ʡ as a uvular *q could indicate it was pharyngeal, since ʔ > q might be an impossible sound change.

In addition to the inventory above, Proto-Koyanic is reconstructed with a set of three laryngeal consonant-like sounds, *x₁ *x₂ *x₃, which almost always occur next to a schwa *ə *ə̄ as part of a syllable nucleus. These laryngeals colour the adjacent schwa in characteristic ways, though the exact resulting vowel quality varies by daughter language. *x₁ gives a close front colouring [ɨ~i~e], *x₂ an open front colouring [ə~e~æ~a~a], and *x₃ a back rounded colouring [ɑ~ɔ~o~u]. The laryngeals are retained in certain phonological environments in some daughter languages with the following reflexes: *x₁ by [x~ɣ~h~ʔ], *x₂ by [χ~ʁ~h~ʔ] and *x₃ by [x~ɣ~ʁ~h~ɦ]. Since there is such a large overlap in their qualities, not much can be said about the original qualities of each laryngeal, only that they were likely fricatives articulated further back than the velum and *x₃ probably had some labialisation.

Voiceless sonorants
The voiceless sonorants are allophones of their voiced counterparts when in a consonant cluster containing *h or following an aspirated plosive or *s. They are not thought to have been phonemic in Proto-Koyanic, but became consonants in their own right in the Qʼachkav and Hnäzb language groups. The distinctive qualities of the voiceless sonorants are nonetheless reconstructible, and are commonly transcribed ⟨m̥ n̥ ɲ̊ ŋ̊ r̥ l̥ ẙ w̥⟩ to make this clear. When clustering with *h, they are often transcribed as single consonants, e.g *hm̥ə́x₃l̥h "blood" may be written *m̥ə́x₃l̥.

Vowels
It has been suggested that the vowels *u *ū and *a *ā had qualities [ʊ ʊː] and [ɑ ɑː] respectively, though this is difficult to reconstruct with such certainty.

Phonotactics
The primary constraint on PKn syllables is dictated by a sonority hierarchy, consonant clusters may never decrease in sonority towards the syllable nucleus. The hierarchy is as follows: Certain other natural groups are also useful to consider:
 * 1) Laryngeal X = {*x₁ *x₂ *x₃}
 * 2) Glide G = {*y *w}
 * 3) Liquid L = {*r *l}
 * 4) Nasal N = {*m *n *ɲ *ŋ}
 * 5) Obstruent O = {*p *t *z *c *k *q *ʡ *pʰ *tʰ *s *cʰ *kʰ *qʰ *h}

Using these groups, the maximal syllable structure can be simply described as symmetrical *BNLZVZLNB, but is more usefully understood both synchronically and diachronically as three segments:
 * Boundary consonant B = {*m *n *ɲ *ŋ *p *t *z *c *k *q *ʡ *pʰ *tʰ *s *cʰ *kʰ *qʰ *h}
 * Nuclear consonant Z = {*x₁ *x₂ *x₃ *y *w}
 * Non-nasal sonorant R = {*y *w *r *l}


 * Onset — *(B)(N)(R)-
 * Nucleus — *-(X)V(Z)-
 * Coda — *-(L)(N)(O)

Onset
Three optional parts composed the syllable onset, with their order constrained by the sonority hierarchy: an initial "boundary" consonant B, a nasal N and a non-nasal sonorant R. Further constraints on the onset applied to pairs of consonants, that is to say that if *B₁N₁- and *N₁R₁- were allowed onsets, then so was *B₁N₁R₁-. There were four laws restricting which biconsonantal clusters were possible in the syllable onset:


 * 1) Medial *-r- and *-y- may only appear following labial, uvular and laryngeal consonants
 * 2) Plosive-nasal onset clusters were allowed only when heterorganic, that is the two consonants have different places of articulation. Thus, clusters like **kŋ- and **tʰn- were forbidden while *cm- and *ʡɲ- are allowed. This rule also prohibited such clusters with "similar" places of articulation, thus **k(ʰ)ɲ-, **t(ʰ)ɲ-, **sɲ-, **zɲ- **c(ʰ)n-, **c(ʰ)ŋ- and **q(ʰ)ŋ- were also forbidden.
 * 3) Nasal-nasal clusters were even more restricted, being allowed only when exactly one of the two nasals is *m, e.g. *mn-, *ɲm- and *ŋm- are all attested. There is no known law preventing *nm-, *mɲ- and *mŋ-, but no such examples are attested. One theory suggests that nasals follow their own sonority hierarchy *n > *m > *ɲ, *ŋ, which would enforce the order of nasals allowed in the onset, but no phonetic justification for this is known. The novel reconstruction of Proto-Koyanic notably rejects even the clusters *mn-, *ɲm- and *ŋm-, replacing them with *nw-, *nʲw-/*ŋʲw- and *ŋw-.
 * 4) Clusters of initial nasals and medial *-w- are forbidden, except *mw-. Examples of *N-w- arising morphologically appear to have neutralised into *mw-. Novel Proto-Koyanic rejects this law, since *Nw- clusters are allowed as per the previous law.

The forbidden clusters were established not just through lack of attestation, but also analysis of certain morphological processes which would avoid their

The table below shows an example for each attested biconsonantal cluster within the onset of a single morpheme in Proto-Koyanic. Greyed out cells indicate clusters forbidden by one of the four laws. Fortition was a property applied to the entire onset cluster and is not phonotactically relevant, so the fortis-lenis obstruent pairs are considered together.

Nucleus
The syllable nucleus had the maximal form *XVZ, where Z = {*x₁ *x₂ *x₃ *y *w}. Offglides were fundamentally vowel-like, unlike onglides which were consonant-like. They are considered part of the nucleus rather than the coda cluster because they participate in various phenomena relating to the vowel, while not interacting with coda consonants:


 * Offglides are frequently involved in monophthongisation and colouring of the nuclear vowel, much like the laryngeals *x₁ *x₂ *x₃
 * Offglides are not constrained by adjacent consonants like the onglides are, any consonant (except a Z consonant) may follow an offglide.
 * Onglides are prone to altering and merging with preceding consonants in daughter languages, whereas offglides have no affect on following consonants
 * It is believed that onglides had voiceless allophones *ẙ *w̥ in fortis onset clusters, whereas offglides were not affected by following fortis consonants and had no such allophones

The nucleus could only contain a laryngeal if the vowel was a schwa, and could not take a second laryngeal, leaving three primary types of nucleus: *V(G), *X[ə/ə̄](G), *[ə/ə̄]X.

There was also thought to be a type of minor syllable which has no vowel and only a single laryngeal *X as its nucleus. These appear mostly in roots and suffixes and are known as light nuclei, in contrast with heavy nuclei described above, in reference to their differing prosodic weights. A light syllable can only occur following a heavy syllable, and can never carry stress. If a light syllable ends up with no preceding heavy syllable, it is promoted to a heavy syllable by insertion of *⟨ə⟩ after its nuclear X. e.g. *√x₁t “the wind, life” surfaces as *x₁ət- in *x₁ə́t.cəm (H́.H) “the wind god” and *x₁ə́t.mnx₃ə (H́.H) “to blow”, but remains *-x₁t in *x₂əm̥.px₃ə̄́.kəx₃.sx₁t (H.H́.H.L) “to kill”. Note that this process is not related to stress whatsoever, but it does allow an underlying light syllable to take the stress if it surfaces as a heavy syllable. The existence of light syllables is still somewhat disputed, with some claiming that the reduced nuclei were not present in PKn, developing later from certain unstressed instances of *Xə.

Taking all of this into account, there are 51 possible syllable nuclei, shown in the table below: There exists a single irregular nucleus, present only in *√x₁us "bird", a common root which appears in multiple stems and of which evidence abounds that this is the most appropriate reconstruction.

Stress
Stress usually falls on the penultimate heavy syllable, but it’s possible to fall on other heavy syllables which have specific morphologically marked stress, e.g. in certain suffixes.

Roots
Roots are a particular morphological unit which can act as a word stem with a class just like any other stem, but are most typically used to derive new stems. The canonical Koyanic root is a single syllable, either heavy or light, but with a strictly laryngeal nucleus, i.e. the allowed nuclei are {*Xə *Xə̄ *ə *ə̄ *əX *ə̄X *X}. Roots are notated with √, e.g. *√mx₃n "to grow, increase".

{*əx₁ *ə̄x₁ *əx₂ *ə̄x₂ *əx₃ *ə̄x₃} regularly alternate with {*i *ī *a *ā *u *ū} when unstressed. This alternation can clearly be seen in compounds using the root *√cʰəx₂r̥h "to think, feel": Note that this applies only to root nuclei, /əX/ and /ə̄X/ can occur unstressed elsewhere. For example, the stem *zə́x₁ɲ̥cʰəx₂ "berry" exhibits unstressed *əx₂.

Derivation
Word stems are typically formed by attaching an affix to a root or compounding roots. Not all words are formed from roots, some words are polysyllabic and contain other vowels but cannot be morphologically broken down, e.g. *tʰuyə̄ “house” and *ir̥luy “ball”. Compounds of two stems are common, with the typical patterns shown below.
 * Noun-verb: A verb with noun as object
 * Verb-noun: A noun which performs a verb
 * Verb-stative: A verb characterised by an adverbial stative
 * Noun-stative: A noun characterised by a stative

Infixation
Verb conjugation makes use of some infixes which are sensitive to phonotactics. The infix is inserted immediately after the first consonant of the base, or attached as a prefix on a vowel-initial base. An epenthetic *⟨ə⟩ may be inserted before the infix if phonotactically required. Some examples of infixation using hypothetical infixes on real reconstructed forms, and their surface phonological forms with prosodic structures, are shown below.

Root-based affixes
There are some derivational affixes used exclusively to derive stems from roots. These are generally prefixes and infixes.
 * *⟨qx₂əq⟩ derives transitive verbs from typically stative roots, e.g. *tə⟨qx₂ə́q⟩x₂w "to speak with, tell" from *√tx₂w "to speak".
 * *ə̄- derives statives from roots with typically transitive meaning, often with an involuntary or passive meaning, e.g. *ə̄́-tʰə̄m "to sink, drown" from *√tʰə̄m "to submerge".

Derivational suffixes
There is also a separate category of derivational suffixes which can be applied to stems or roots to derive new stems, usually involving a change of word class. A selection of reconstructed suffixes are shown below.

Nouns
Proto-Koyanic had several cases depending on the animacy of the noun. The animate series of cases also marks plurality in the accusative, ergative, oblique and genitive cases.

Verbs
Verbs are reconstructed to have been optionally transitive, that is they had a single core argument in the absolutive case, with optional additional arguments marked for other roles.

Verb stems were inflected with a large set of prefixes, infixes and suffixes. Each major AQ language uses these affixes in slightly different constructions and patterns, meaning the overall system of conjugation at the time of Proto-Koyanic is not known. The morphemes which have been reconstructed are shown below, though how they interacted is not clear, so this table should not be assumed to represent individual forms of a single conjugation paradigm.

Statives
Statives, like verbs, could be the predicate of a clause, but took only a single argument. Stative stems have a similarly reconstructed set of inflectional affixes, shown below.

Word order
Notable features of Proto-Koyanic are the rich morphological system in form of affixes in both verbs and noun, featuring two genders, inanimate and animate nouns are labelled with asymmetric morphology, inanimate nouns are the least marked ones they do not feature plural numbers. As opposed, animate nouns are the most marked ones with three kind of genitives working together, and marking the singular absolutive. Proto-Koyanic word was flexible, but basic declarative sentences typically had the structure SVO.

Relative clauses
Relative clauses in Proto-Koyanic carries either zero morphology or it is used the particle *məx₂ŋ to express relative clauses. There's also a three way relative clauses take in later Koyanic languages, using conditional conjugation in the transitive verb we can obtain something quite related to a relative clause. In Gäj the irrealis becomes the basis of the three main verb conjugations, the "irrealis" which features a subjunctive form and marked future tense form.

Pronouns
First and second person pronouns in Proto-Koyanic distinguished three cases, absolutive, genitive and instrumental; while the third person pronouns have additional ergative and dative marking.

Numerals
Proto-Koyanic, like all its descendants, used a base-10 system of numerals. The ten basic numerals are shown below:

Relation to Upic
The numerals 1-5 are thought to be related to those forms reconstructed for Proto-Upic, the common ancestor of the Upic languages. This relationship has proven useful in dating Proto-Upic and placing bounds on the time period of early Upic splits.

Alternative reconstructions
The form of Proto-Koyanic presented in this article is the most well established and commonly used, but not the only possible reconstruction. Various other reconstructions of the language may sometimes appear on other pages of the wiki or elsewhere, a few of which are briefly discussed below.

Original reconstruction
The first full reconstruction of Proto-Koyanic was largely the same as the one currently used, establishing most of the core features. At this time, the language was known as Proto-Arklobu-Qachkav, as a lack of data made understanding the phylogeny of the family difficult and it was an attempt to reconstruct the most recent common ancestor of Arklobu and Qʼachkav.

A few key differences between the original and current reconstructions are shown below:


 * The vowel qualities were slightly more speculative, suggesting *ɑ *ɑː *ʊ *ʊː for what are now usually given the less phonetically precise labels *a *ā *u *ū.
 * Less emphasis was put on the importance and role of stress in the formation of vowel qualities, now generally thought to be an integral part of Proto-Koyanic's phonology.
 * The nature of the alternation between the cardinal vowels and laryngeal nuclei was not as well understood.
 * Voiceless sonorants were considered completely phonemic and in slightly different distributions, leading to various more complex reconstructed forms which have been proven unnecessary by newer analysis. Despite this, the voiceless glides *ẙ *w̥ were initially not considered at all, and later appeared only rarely.

Late Proto-Koyanic
Late Proto-Koyanic (LPKn) was an attempt to reconstruct the ancestor to all Koyanic languages except the Duodoseic branch, a group sometimes called the Nuclear Koyanic languages. The motivation for this exercise was the undoubted fact that the vast majority of Koyanic languages reflect a common set of sound changes which remodelled Proto-Koyanic's laryngeal system into a large inventory of contrastive vowels. The approach taken was essentially an extension and reinterpretation of more traditional reconstructions of PKn, positing a few sound changes which brought it closer in line with some later Proto-languages. Late Proto-Koyanic ultimately proved an unnecessary complication in understanding Koyanic development and is generally no longer used, but was incidentally of great benefit to an entirely novel reconstruction of true Proto-Koyanic, detailed further below.

Three characteristic changes involving the laryngeals *x₁ *x₂ *x₃ were assumed to have occurred concurrently, forming the basis of Nuclear Koyanic:
 * 1) Laryngeal colouring of schwas, generating pre-glottalised and post-glottalised vowels *ˀi *ˀī *ˀa *ˀā *ˀu *ˀū *iˀ *īˀ *aˀ *āˀ *uˀ *ūˀ
 * 2) Vocalisation of laryngeals into fully glottalised vowels *ĩ *ã *ũ
 * 3) Merger of laryngeals into a single consonant *x

These changes represent an example of transphonologization, where the contrastive feature which was carried by the laryngeal consonant in Proto-Koyanic is shifted to the coloured vowels, but no overall change in phonemic contrast has occurred. In contrast, PAQ is thought to have undergone structural changes to the phonology, developing glottalised obstruents and new vowel qualities, while lacking vowel phonation. The proposed LPKn changes might not actually represent any innovation or meaningful alteration to the phonemic contrasts present in the supposedly earlier Proto-Koyanic, and so they are perhaps more sensibly understood as a reanalysis of Proto-Koyanic more than an actual historical development. For this reason, Late Proto-Koyanic is no longer considered a canonical historical language stage, but went on to form the basis of a completely new reconstruction of Proto-Koyanic, detailed below.

The resulting remodelled phonology retains many features of Proto-Koyanic, but is structurally distinct. It was also suggested that LPKn may have featured the development of true palatals *c *cʰ from older palatalised velar consonants *kʲ *kʲʰ, an idea which eventually led to the novel reconstruction.

Novel Proto-Koyanic
The novel reconstruction, often called Novel Proto-Koyanic (NPKn) is intended to comprehensively explain as many irregularities and inconsistencies with previous reconstructions as possible, while remaining a naturalistic description of a language. This reconstruction is based on the work done on Late Proto-Koyanic, and focuses more on features absent from Qʼač and Gäj languages which are unique to earlier diverging groups like Duodoseic and Kát.

Despite aiming to be as evidence-based as possible, the reconstructed phonology is much more speculative than traditional reconstructions, featuring several controversial changes yet to be widely accepted:
 * Consonants are considered in two articulatory groups, central and peripheral, with each group having unique properties distinguishing it from the other group.
 * Plosives are reconstructed with an unspecified fortis-lenis distinction, usually assumed to be contrastive voice in most circumstances, with aspiration considered a later development of the voiceless plosives.
 * Palatals and sibilants are reinterpreted as palatalised plosives to explain a few odd reflexes and patterns observed in early Koyanic languages.
 * The laryngeal consonants *x₁ *x₂ *x₃ are rejected completely, with a rich system of vowel phonation reconstructed in their place.
