The Northern Jê

Tapayúna. Together with Panará (and its predecessor, Southern Kayapó), they form the Goyaz branch of the
family.

The term Northern Jê has been sometimes used to refer to a broader group of languages, which also includes Panará and Southern Kayapó.[3]: 547 [2] In this article, the label Northern Jê is used in the narrow sense (that is, excluding Panará and Southern Kayapó).

Phonology

The Northern Jê languages have been noted for their outstanding relation between the nasality vs. orality of the nuclei and the allophonic realization of the adjacent nasal consonants. In

Kĩsêdjê,[5]: 127–8  for instance, underlying nasal consonants surface as partially oral (for example, /m/ [mb]) if the nucleus of the syllable is oral; this allophony pattern has been characterized by Wetzels and Nevins (2018) as nasal shielding.[6]
: 860 

All Northern Jê languages have similar phonotactic restrictions. Typically, the maximal syllable is CRWVC, where C stands for a

Timbira
varieties only have CRVC and CWVC, but not *CRWVC.

Codas

In all Northern Jê languages, the syllables may be either open or closed. The maximum number of consonants in the coda position is one (that is, only simplex codas are allowed). The nasal codas which follow oral nuclei may be subject to nasal shielding in some languages, whereby the initial phase of the nasal consonant is oralized, as in

Apinajé /om/ [ˈobm] ‘its powder’.[4]
: 40 

In most (if not all) Northern Jê languages, codas may be followed by epenthetic vowels called

Mẽbêngôkre
, the echo vowels are written out only after r, whereas in the remaining languages the echo vowels are not reflected in writing.

The inventory of Proto-Northern Jê codas comprised nine phonemes, whose reflexes in the daughter languages are shown below.

Morphology

Finiteness morphology

In all Northern Jê languages verbs inflect for finiteness and thus have a basic opposition between a finite form and a nonfinite form. Finite forms are used in matrix clauses only, whereas nonfinite forms are used in all types of subordinate clauses as well as in some matrix clauses (at least in some languages). Nonfinite forms are most often formed via suffixation and/or prefix substitution.[7] Some verbs (including all descriptives with the exception of *kato ‘to exit’, whose nonfinite form is *kator) lack an overt finiteness distinction.

For the protolanguage, five nonfinite suffixes have been reconstructed: *-r (the most common option, found in many transitive and intransitive verbs), *-ñ (found in some transitive verbs), as well as *-k, *-m, and *-c (found in a handful of intransitive verbs which take a nominative subject when finite).[7]: 543 

Nonfinite suffixes

*mõ *mõr to go (plural)
*bĩ *bĩr to kill (singular)
*krẽ *krẽr to eat (singular)
*karê *karêr to weed
*japrô *japrôr to take away
suffix *-ñ
*põ *põñ to rub
*kê *kêñ to grate
*kwỹr *kwỹñ to break
*kumbə *kumbəñ to gnaw
*kaĵô *kaĵôñ to tear

*tẽ *tẽm to go (singular)
*ijkõ *kõm to drink
*ĵa *ĵãm to stand (singular)
suffix *-c
*aŋgî *ŋgjêc to enter (plural)

In a handful of verbs, all of which end in an underlying stop, the nonfinite form does not receive any overt suffixes, but it is nevertheless distinct from the finite form because the latter lenites the stem-final consonant (*-t, *-c, *-k*-r, *-j, *-r).[7]: 544 

Nonfinite suffixes

*tjêr *tjêt to burn
*ŋõr *ñõt to sleep
*bôj *bôc to arrive
*do=pôj *do=pôc to extract (plural)
*kar *kak to cough
*pôr *pôk to burn, to ignite
*jarkjêr *jarkjêk to yawn

Palatalizing prefix

A small set of verbs form their nonfinite forms by employing one of the aforementioned processes and a morphophonological process whereby the onset of the stressed syllable becomes palatal, and the nucleus of the stressed syllable is raised (if possible); this has been attributed to the influence of an underlying palatalizing nonfinite prefix.[7]

*aˀtĩ *jəˀk to sneeze
*(krə̃)ˀta *(krə̃)ˀcyr to cut off (singular)
*c-anẽ *c-añỹr to do so, to say so

Prefix substitution or loss

In addition to the aforementioned processes, the finiteness inflection may involve prefix substitution or loss. For example, the valency-reducing prefixes are *a(j)- (

antipassive) in finite verb forms, but *bi(t)- and *jə-/*ju-, respectively, in the nonfinite forms.[7]
: 541, 544  In addition, some verbs which denote physiological activities or movement have a prefix (*ij- and *a-, respectively) in their finite forms but not in the nonfinite form.

Person inflection and case

In all Northern Jê languages verbs,

agentive (unmarked) noun phrases (including personal pronouns) in finite clauses, or by ergative
phrases in nonfinite clauses.

In the table below, the label class II refers to a subclass of vowel-initial stems which take the thematic consonant */ĵ-/ in the basic (uninflected) form as well as in some inflected forms (e.g. *∅-j-arkwa ‘my mouth’, *ba-j-arkwa ‘our mouths’, *rop j-arkwa ‘the jaguar's mouth’) but not in others (*g-arkwa ‘your mouth’, *c-arkwa ‘his/her/its mouth’). The archaic allomorphs *∅-/ĵ-/ (first person, class II) and *g- (second person, class II) are only marginally preserved across Northern Jê: the former is preserved in

Nominal number

In most Northern Jê languages, nouns which denote human beings may receive an overt collective plural suffix (Proto-Northern Jê -jê). Its reflexes have been attested in

Canela
(-jê), among others. In fact, this suffix is part of many names of Northern Jê peoples, as in Kĩsêd, Parkatê, Pykob (self-denomination Pyhcopji), Apànkra, and is the ultimate origin of the term itself.

Derivational morphology

Productive affixes

All Northern Jê languages make use of at least one diminutive suffix (Proto-Northern Jê *-re) and of an augmentative suffix (*-ti), which may occur in nouns and descriptives.[11]: 257–9 [9]: 36–7 [10]: 69, 79–81 [12]: 52  These are widely used in the names of animal and plant species.

For most Northern Jê languages,

Mẽbêngôkre, where djà and djwỳj have been claimed to be relational nouns meaning ‘container’ and ‘master’, respectively:[14]
: 88 

In the literature on other Jê languages <...>, these have been considered to be an instrument and an agent nominalizer, respectively. Our contention is that what the "nominalizers" attach to is already nominal <...>, and they themselves are no more than the semantically bleached nouns dʒʌ ‘container’ and dʒwɤj ‘master’.

Non-productive affixes

In Northern Jê languages, many predicates appear to contain fossilized prefixes of different shapes (such as Proto-Northern Jê *ka-, *ñõ-, *ku-, *py-/*pu-, *ja-, *ju-, *ñĩ-), whose semantic contribution is not always straightforward. These have been variously referred to as formatives[13]: 116–28  or transitivity prefixes.[7]: 539–40 

Syntax

All Northern Jê languages are head-final.

Morphosyntactic alignment

Prototypically, finite

agentive case[1]), whereas the patients of transitive verbs (P) and the sole arguments of the remaining intransitive predicates (SP) receive the absolutive case (also called internal case[1]).[15] In addition, transitive verbs are subdivided into two classes according to whether the third person patient is indexed as absolutive (Proto-Northern Jê *c-) or accusative (Proto-Northern Jê *ku-),[7]: 538–9  which has been described as an instance of a split-P alignment.[1]: 272  There are only several dozen of transitive verbs which take an accusative patient, all of which are monosyllabic[13]: 181, 219  and have distinct finite and nonfinite forms.[5]: 13, 133  It has been suggested that all transitive verbs which satisfy both conditions (monosyllabicity and a formal finiteness distinction), and only them, select for accusative patients,[7]
: 538  while all remaining transitive verbs take absolutive patients in Northern Jê.

Nonfinite clauses (including all subordinate clauses) are headed by nonfinite verbs and are

postpositional phrases, whereas the patients of transitive verbs (P) and the sole arguments of all intransitive predicates (S) receive the absolutive case (also called internal case[1]).[15] The ergative-absolutive alignment in subordinate clauses is found in all Northern Jê languages and is reconstructed by Castro Alves (2010) for Proto-Northern Jê.[15]

In addition, in some Northern Jê languages former biclausal constructions (with an ergatively organized subordinate clause and a split-S matrix clause) have been reanalyzed as monoclausal, resulting in some cases in constructions with a

Classes of predicates

The following table summarizes the proposed classes of predicates in Northern Jê languages.[7]

argument structure in finite clauses type examples
transitive verb (*ku-class) *krẽ ‘to eat’ (singular)'
transitive verb (default) *côk ‘to paint’
SNOM (active) intransitive verb *tẽ ‘to go’ (singular)
SABS descriptive *ŋgryk ‘to be angry’
ExpDAT
monovalent verbum sentiendi *prə̃m ‘to be hungry’
ExpDAT StimulusABS
bivalent verbum sentiendi *kĩñ ‘to like’

Transitive verbs

In the Northern Jê languages, transitive verbs take accusative or absolutive patients in finite clauses, depending on the verb class. In nonfinite clauses, all transitive verbs take absolutive patients. Note that nouns do not receive any overt marking either in the accusative or in the absolutive case; the difference between these two cases is seen in the third person index, which is reconstructed as *ku- in the accusative case and as *c- in the absolutive case.

The transitive verbs which index their patient in the accusative case (in finite clauses) are known as *ku-verbs. All *ku-verbs are monosyllabic[13]: 181, 219  and have distinct finite and nonfinite forms.[5]: 13, 133  The remaining transitive verbs index their patient in the absolutive case. All verbs that belong to this class satisfy at least one of the following conditions:

  • they contain at least two syllables (for example, *pumbu ‘to see’, *kacô ‘to suck’, *kuˀcõ ‘to wash (solid objects)’),
  • their finite and nonfinite forms are identical (for example, *côk ‘to paint’, *kre ‘to plant’, *ĵũn ‘to insult’).

Finite *ku- verbs further differ from all other transitive verbs in that under certain circumstances they index their

Canonical (active) intransitive verbs

Descriptives

All Northern Jê languages have intransitive predicates which take absolutive (rather than nominative) subjects, known as descriptives. They have been variously described as verbs[11][13][15] or nouns.[14] An example of a reconstructed Proto-Northern Jê clause headed by a descriptive is *ij-ŋgryk ‘I am angry’ (literally 1SGABS-be.angry).

Verba sentiendi and dative subjects

Verba sentiendi with

Kĩsêdjê.[5]
: 31–3 

Monovalent verba sentiendi take only one argument (

experiencer), which is encoded by a dative postpositional phrase, as in the following reconstructed example: Proto-Northern Jê *ij-mə̃ prə̃m ‘I am hungry’[7]
: 537  (literally 1SGACC-DAT hunger).

Bivalent verba sentiendi take two arguments. The

experiencer is encoded by a dative postpositional phrase, and the theme receives the absolutive case, as in the following reconstructed example: Proto-Northern Jê *ij-mə̃ a-kĩñ ‘I like you’[7]
: 537  (literally 1SGACC-DAT 2ABS-fun).

Lexicon

Predicate number

The Northern Jê languages commonly employ different lexemes for the so-called singular and plural predicates. As Nikulin and Salanova (2019) put it,

Archetypally, certain verbs have distinct forms according to the number of the absolutive argument (if the argument in question is not human, number is not marked independently on it but rather only on the verb). In addition, verbal number can indicate repeated action, even if all participants are singular. Further nuances of the plural include a more prolonged or sluggish carrying out of an action, incomplete or ineffective carrying out of the action, and perhaps even indirect evidence for the action.[7]: 540 

There are several dozen pairs of predicates which contrast in number. Plural predicates are not regularly derived from their singular counterparts but are rather expressed by unrelated lexemes (in a handful of verbs, it is possible to the fossilized prefix *ja- encoding plural). Some examples of Proto-Northern Jê verbs which differ in number include:[7]: 541
