Case system

Version: 1.0
Last Updated: May 26, 2026

This section is part of our living public grammar of Avar and is regularly updated to reflect the latest linguistic research, database enhancements, and morphological analyses.

Avar features an exceptionally rich and typologically complex case system, comprising 4 grammatical (core) cases and a structured 20-case spatial (local) case grid (organized into 5 series based on location, crossed with 4 directional types). Syntactically, Avar is characterized by a strict ergative-absolutive alignment where the encoding of core nominal arguments depends directly on the transitivity of the governing verb.

Core Grammatical Cases

The core grammatical cases mark the structural relations between arguments and verbs, expressing primary syntactic roles like subjects, direct objects, possessors, and recipients.

1. Absolutive (Nominative)

The Absolutive case is the morphologically unmarked base form (zero marking) and serves as the dictionary citation lemma. It is syntactically multi-valent, encoding:

  1. The subject of an intransitive verb.
  2. The direct object of a transitive verb.
  • вас вачӀана [was ˈwa.t͡ʃʼa.na] — vas w-a-t͡ʃʼa-na (boy.ABS I-come-AOR) "the boy came (intransitive subject)"
  • инсуда вас вихьана [in.ˈsu.da was ˈwi.xa.na] — ins-u-da vas w-ixa-na (father-OBL-LOC.I boy.ABS I-see-AOR) "the father saw the boy (transitive direct object of a perception verb, governing a Locative I subject)"
2. Ergative

The Ergative case is the active argument marker, formed on the noun oblique stem using suffixes -с (Declension I), -лъ (Declension II), or -ца (Declension III). It primarily encodes:

  1. The subject (agent) of a transitive verb.
  2. An instrumental, causal, or manner oblique modifier (especially with inanimate nouns).
  • инсуца вас вачана [in.ˈsu.t͡sa was ˈwa.t͡ʃa.na] — insu-t͡sa vas w-at͡ʃa-na (father-ERG boy.ABS I-lead-AOR) "the father (ergative agent) brought/led the boy"
  • хонжроца квен бахана [χon.ˈʒo.t͡sa kwen ˈba.χa.na] — χonʒ-ro-t͡sa kwen b-ax-a-na (dagger-OBL-ERG food.ABS III-cut-EP-AOR) "(he) cut the food with a dagger (ergative instrument)"
3. Genitive

The Genitive case is the primary attributive marker, formed by appending -ул or -л to the Ergative form. It denotes a rich array of nominal relations:

  1. Possession: васасул рукъ [wa.ˈsa.sul ruq] — vas-a-s-ul ruq (boy.OBL-ERG-GEN house) "the boy's house"
  2. Material: меседил зурма [me.ˈse.dil ˈzur.ma] — mesed-i-l zurma (gold.OBL-GEN zurna) "golden zurna"
  3. Partitive: гъотӀол гӀаркьел [ʁo.ˈtʼol ˈʕar.kʼel] — ʁotʼ-o-l ʕarkʼel (tree.OBL-GEN branch) "the branch of the tree"
  4. Temporal: роол къо [ro.ˈol qʼo] — ro-o-l qʼo (summer.OBL-GEN day) "a summer day"
  5. Indirect Object (Source): цӀолбол чагъир гьабуна [t͡sʼo.ˈlbol t͡ʃa.ˈʁir ˈha.bu.na] — t͡sʼolbo-l t͡ʃaʁir ha-b-u-na (grape-GEN wine.ABS make-III-EP-AOR) "made wine from grapes"
Attributive Chains (Recursive Genitives)

Because genitives are attributes, Avar allows them to stack recursively, building complex pre-nominal chains:

  • инсул вацасул ясалъул рукъ [inˈsul waˈt͡sa.sul jaˈsa.ɬul ruq] — ins-ul wac-a-s-ul jas-a-l-ul ruq (father-GEN brother-OBL-ERG-GEN daughter-OBL-ERG-GEN house) "the house of the father's brother's daughter"
4. Dative

The Dative case is formed by adding -е or -есе to the Ergative stem. Syntactically, it encodes:

  1. Experiencer Subject: With perception, mental, or affective verbs (such as бокъизе "to love/like", хиралъизе "to become dear", рихине "to hate"), the subject is put in the Dative while the target of the emotion is in the Absolutive.
  2. Recipient / Addressee: The indirect object of ditransitive verbs.
  • ГӀусмание гӀурччинлъи бокьулаан [ʕus.ˈma.ni.e ʕur.ˈt͡ʃʼin.ɬi bo.ˈt͡ɬʼːu.la.an] — ʕusman-i-e ʕurt͡ʃʼin-ɬi b-oƛʼ-ul-a-an (Osman-OBL-DAT greenery.ABS III-love-ITER-EP-IMPF) "Osman loved greenery (dative subject)"
  • гьелъ ГӀашурае баркала кьуна [heɬ ʕa.ˈʃu.ra.e bar.ˈka.la ˈt͡ɬʼːu.na] — he-ɬ ʕaʃura-e barkala ˈt͡ɬʼːu-na (she-ERG Ashura-DAT thanks.ABS give-AOR) "she thanked Ashura (dative recipient)"
5. Instrumental

The Instrumental case expresses the means, path, or instrument of an action, typically marked by the suffix -лъул.

  • носолъул кӀватӀи бахана [no.ˈso.ɬul kʼwa.ˈtʼi ˈba.χa.na] — nos-o-ɬul kʼwatʼi ˈba.χa-na (knife-OBL-INSTR flatbread.ABS III-cut-EP-AOR) "(he) cut the flatbread with a knife"
Morphological Declension Types

Avar nouns, substantivized adjectives, and inflecting verbals are divided into three distinct morphological declension classes that dictate the phonological realization and suffixation of the core grammatical cases (particularly the Ergative, Genitive, and Dative):

1. Declension I (Suffix -с / -ас)

This declension is restricted to masculine human nouns (Class I). The suffix is phonologically conditioned by the oblique stem ending:

  • Vowel-final oblique stems: Suffix -с attaches directly.
    • Гъазияв [ʁa.zi.ˈjaw] "Ghazi (Absolutive)" → oblique stem Гъазия- → Ergative: Гъазияс [ʁa.zi.ˈjas].
  • Consonant-final oblique stems: Suffix -ас is attached.
    • вас [was] "boy (Absolutive)" → oblique stem васа- → Ergative: васас [wa.ˈsas].
  • Genitive & Dative Formation: The Genitive and Dative suffixes stack directly on top of the Ergative stem:
    • Genitive: Suffix -ул → васасул [wa.ˈsa.sul] (vas-a-s-ul) "boy's"
    • Dative: Suffix -е → васасе [wa.ˈsa.se] (vas-a-s-e) "to the boy"
2. Declension II (Suffix -лъ / -алъ)

This declension applies to feminine human nouns (Class II), borrowed Class III neuter nouns, and native Class III nouns ending in vowels:

  • Vowel-final oblique stems: Suffix -лъ attaches directly, often resolved with a glide.
    • Баку [ba.ˈku] "Baku (Absolutive)" → oblique stem Бакуя- → Ergative: Бакуялъ [ba.ˈku.jaɬ].
  • Consonant-final oblique stems: Suffix -алъ is attached.
    • яс [jas] "girl (Absolutive)" → oblique stem яса- → Ergative: ясалъ [ja.ˈsaɬ].
    • стол [stol] "table (Absolutive)" → oblique stem стола- → Ergative: столалъ [sto.ˈlaɬ].
  • Genitive & Dative Formation: The Genitive and Dative suffixes stack directly on top of the Ergative stem:
    • Genitive: Suffix -ул → ясалъул [ja.ˈsa.ɬul] (jas-a-l-ul) "girl's"
    • Dative: Suffix -е → ясалъе [ja.ˈsa.ɬe] (jas-a-l-e) "to the girl"
3. Declension III (Suffix -ца / -ица)

This declension encompasses proper names ending in vowels, consonant-final names, irregular kinship terms, and native Class III common nouns that show significant oblique stem shifts:

  • Direct suffixation: Takes -ца directly after vowel stems or -ица after consonants.
    • Муса [mu.ˈsa] "Musa (Absolutive)" → Ergative: Мусаца [mu.ˈsa.t͡sa].
    • АхӀмад [a.ˈħmad] "Akhmad (Absolutive)" → Ergative: АхӀмадица [a.ˈħma.di.t͡sa].
  • Oblique stem alterations: Operates on highly modified oblique stems.
    • цер [t͡ser] "fox (Absolutive)" → oblique stem цара- → Ergative: цараца [t͡sa.ˈra.t͡sa].
    • эмен [e.ˈmen] "father (Absolutive)" → oblique stem инсу- → Ergative: инсуца [in.ˈsu.t͡sa].
  • Genitive & Dative Formation: Unlike Declensions I and II, Genitive and Dative endings in Declension III do not stack on the Ergative suffix. Instead, the Ergative suffix -ца / -ица is substituted by Genitive -л / -ул / -дул and Dative -е / -дуе:
    • инсуца "father [ERG]" → Genitive: инсул [in.ˈsul] (not *инсуцасул), Dative: инсуе [in.ˈsu.e] (not *инсуцасе).
    • цараца "fox [ERG]" → Genitive: царал [t͡sa.ˈral], Dative: царае [t͡sa.ˈra.e].
    • цица "bear [ERG]" → Genitive: цидул [t͡si.ˈdul], Dative: цидуе [t͡si.ˈdu.e].

The Spatial Case System (Locative Series)

Avar possesses a highly systematic grid of 20 spatial cases designed to express spatial orientation and movement. The grid is formed by crossing 5 Spatial Series (indicating spatial relationship/location) with 4 Directional Case Types (indicating movement relative to that location):

The Spatial Grid Matrix
Series Spatial Meaning Locative (LOC) "Where?" Allative (ALL) "Whither?" Elative (ELAT) "Whence?" Translative (TRANSL) "Through?"
Series I (-д-) On (surface contact) -да -де -даса -дасан
Series II (-хъ-) Near / At (proximity) -хъ -хъе -хъа -хъан
Series III (-лъ-) In (dense medium/liquid) -лъ -лъе -лъа -лъан
Series IV (-кь-) Under (subessive) -кь -кье -кьа -кьан
Series V (-у-) In (hollow space) -ув / -яй / -об -убе / -яйе / -обе -уса / -яса / -оса -усан / -ясан / -осан
Spatial Series Exemplified
Series I: Surface Contact (On / Onto / From On)

Used when an object resides on or makes surface contact with another.

  • школалда [ʃkoˈlal.da] — ʃkola-l-da (school-OBL-LOC.I) "at / in school"
  • Бакуялде ана [baˈku.jal.de ˈa.na] — baku-ya-l-de a-na (Baku-OBL-ERG-ALL.I go-AOR) "went to Baku"
  • шагьаралдаса [ʃaˈha.ral.da.sa] — ʃahar-a-l-da-sa (city-OBL-ERG-LOC-ELAT) "from the city"
Series II: Proximity (Near / Toward / From Near)

Used to denote being in the immediate vicinity of an object.

  • рукъалъухъе [ruˈqa.ɬu.χe] — ruq-a-l-u-χe (house-OBL-ERG-GEN-ALL.II) "approaching the house"
Series III: Interior / Dense Medium (In / Into / Out of)

Used for placement inside liquids, granular substances, dense forests, or among a group of people.

  • салулъ [saˈluɬ] — sal-u-ɬ (sand-OBL-LOC.III) "in the sand"
  • лъимулъ [ɬiˈmuɬ] — ɬim-u-ɬ (water-OBL-LOC.III) "in the water"
  • гӀурусазулъ [ʕu.ruˈsa.zulɬ] — ʕurus-a-z-u-ɬ (Russian-OBL-PL-GEN-LOC.III) "among the Russians"
Series IV: Subessive (Under / To Under / From Under)

Used for positions directly underneath an object.

  • ганчикь [ganˈt͡ʃikʼ] — gant͡ʃ-i-kʼ (stone-OBL-LOC.IV) "under the stone"
Series V: Inessive Hollow Space (In / Into / From Inside)

Used for hollow three-dimensional spaces (rooms, boxes, clothing, tents). Unique to Avar, the Locative V case incorporates the grammatical class marker (-в, -й, -б, -р) to show gender agreement with the absolutive noun argument:

  • чадиралъув вукӀана [t͡ʃa.di.ˈra.ɬuw ˈwu.kʼa.na] — t͡ʃadir-a-l-u-w ˈw-ukʼ-a-na (tent-OBL-ERG-GEN-LOC.V.I I-be-EP-AOR) "he (Class I) was inside the tent"
  • чадиралъуй йикӀана [t͡ʃa.di.ˈra.ɬuj ˈji.kʼa.na] — t͡ʃadir-a-l-u-j ˈj-ikʼ-a-na (tent-OBL-ERG-GEN-LOC.V.II II-be-EP-AOR) "she (Class II) was inside the tent"
  • чадиралъуб букӀана [t͡ʃa.di.ˈra.ɬub ˈbu.kʼa.na] — t͡ʃadir-a-l-u-b ˈb-ukʼ-a-na (tent-OBL-ERG-GEN-LOC.V.III III-be-EP-AOR) "it / the animal (Class III) was inside the tent"

  • рокъосан [ro.ˈqʼo.san] — roq-o-san (house-OBL-TRANSL.V) "through the house / out from the house"
Syntactic Multi-valency of Spatial Cases (Series I-IV)

While Series V is strictly spatial, Series I-IV are highly multifunctional. In specialized modal, sensory, or experiential syntactic constructions, spatial cases function as grammatical subjects or direct objects:

Spatial Cases as Subject
  • Нижер инсуда мун лъала. [ni.ˈʒer in.ˈsu.da mun ˈɬa.la] — niʒ-er ins-u-da mun ɬa-la (we-GEN father-OBL-LOC.I you.ABS know-PRES) "our father (locative subject) knows you"
  • ХӀамидидаса кинабго росу рази букӀана. [ħa.mi.ˈdi.da.sa ˈki.nab.go ro.ˈsu ra.ˈzi ˈbu.kʼa.na] — ħamid-i-da-sa kinab-go rosu razi b-ukʼ-a-na (Gamid-OBL-LOC-ELAT.I all-EMPH village.ABS pleased III-be-EP-AOR) "the whole village was pleased with Gamid (elative subject)"
Spatial Cases as Object
  • Мохмохида нах бахунге. [moχ.mo.ˈxi.da nax baˈχun.ge] — moχmoχ-i-da nax b-ax-u-n-ge (fat-tail-OBL-LOC.I oil.ABS III-grease-CONV-PL-NEG) "don't grease the fat-tail (locative object) with oil"
  • Дур хонжрокьа хӀинкъулев чи гьечӀо. [dur χon.ʒo.ˈkʼa ˈħi.nqu.lew t͡ʃi ˈhe.t͡ʃʼo] — dur χonʒ-ro-kʼa ħinqu-le-w t͡ʃi he-t͡ʃʼo (you.GEN dagger-OBL-ELAT.IV fear-PART-I person.ABS be-NEG) "there is no person who fears your dagger (elative object)"
Case Stacking

A highly advanced feature of Avar morphology is recursive case stacking (double declension). Because spatial series bases are historically built on the Genitive stem (which represents an oblique adjective), Avar can stack relational and spatial case markers sequentially on a single nominal root to denote complex relative spatial relations:

Root → Genitive Suffix → Locative Suffix → Ablative Suffix

  • рукъулдаса [ruˈqul.da.sa] — ruq-ul-da-sa (house-GEN-LOC.I-ABL) "from inside the house's (surface)"
  • рукъулдасан [ruˈqul.da.san] — ruq-ul-da-san (house-GEN-LOC.I-ABL-TRANSL) "through/via the surface of the house's (something)"
  • инсухъан [inˈsu.χan] — ins-u-χ-an (father-OBL-LOC.II-ABL-TRANSL) "originating from/via the father's custody"
Case Inflection in Other Parts of Speech

Avar's case system is a universal morphosyntactic framework that inflects diverse parts of speech beyond standard nouns:

1. Pronouns

Avar personal pronouns represent the most morphologically complex and highly suppletive elements in the language. Core singular arguments undergo complete stem suppletion when moving from Absolutive to Oblique cases:

  • Absolutive: дун [dun] "I" // мун [mun] "you"
  • Ergative: дица [diˈt͡sa] "by me" // дуца [duˈt͡sa] "by you"
  • Genitive: дица → дил [dil] "my" // дуца → дур [dur] "your"
  • Dative: дица → дие [diˈe] "to me" // дуца → дуе [duˈe] "to you"

Demonstrative and relative pronouns agree in grammatical class with their referents and inflect fully via oblique stems (гьеб "this [III]" → гьелъ [ERG] → гьелъул [GEN]).

2. Adjectives

Adjectives do not possess inherent case. When modifying a noun, they stay in their dictionary form in the direct Absolutive case. However, when an adjective is substantivized (functioning independently as a noun head), it inflects fully through the case system, adopting the oblique singular suffixes (-асу- for masculine, -ал- for feminine/neuter):

  • лъикӀав [ɬiˈkʼaw] "good (Absolutive)" → лъикӀасе [ɬiˈkʼa.se] (good.OBL-DAT) "to the good one"
3. Numerals

Numerals remain unchanged when functioning as attributes. When substantivized (standing in for objects), they inflect under Declension II/III, taking standard oblique suffixes:

  • кӀиго [ˈkʼi.go] "two" → кӀигоялъ [ˈkʼi.go.jaɬ] (two-OBL-ERG) "by the two"
4. Masdars and Participles

Because Masdars are verbal nouns, they declinate as standard nouns (usually under Declension II/III). Participles take on standard adjectival declensions when substantivized:

  • цӀализе "to read" → цӀали "reading (Nom)" → цӀалиялъ [t͡sʼaˈli.jaɬ] (reading-ERG) "by reading"
  • цӀалулев "reading person" → цӀалулесе [t͡sʼa.luˈle.se] (reading-OBL-DAT) "to the reader"
Syntactic Roles of Cases

The selection of nominal cases is strictly governed by the syntactic structure and verb valency:

Core Subject/Object Mappings
  • Intransitive Verbs: Govern an Absolutive subject (вас вачӀана).
  • Transitive Verbs: Govern an Ergative subject and an Absolutive direct object (инсуца вас вачана).
  • Experiencer Verbs: Govern a Dative or Locative subject and an Absolutive target (ГӀусмание гӀурччинлъи бокьулаан).
Indirect Object Government

Beyond core arguments, specific verb classes strictly govern oblique and spatial cases to mark the indirect object:

  • Locative I (-да): Used for targets of emotion (ццин бахъизе "to get angry at"), objects of physical impact (кьабизе "to hit"), and points of comparison.
  • Ablative I (-даса) / Ablative IV (-кьа): Used for sources of fear or shame (хӀинкъизе "to fear", нечезе "to be ashamed of"), as well as objects of deprivation or defense.
  • Locative III (-лъ): Used for reciprocal contention, arguing, or physical clashing (речӀчӀизе "to shoot/throw at", къацандизе "to argue with").
  • Series II (-хъ / -хъе / -хъа): Used for objects of sensory or mental perception, asking, and physical capability.
Adverbial Modifiers

Cases are extensively utilized to form adverbial adjuncts expressing time, reason, and purpose:

  • Ergative: Used to denote the duration of time (анкьаз "for weeks") and abstract cause/reason (хӀинкъиялъ "out of fear").
  • Dative: Used to indicate purpose or target (кумекалъе "for help", нилъее "for us").
  • Translative: Used to indicate causal path or physical trajectory.
