Cases

The nominative constitutes the unmarked base of the Neo-Etruscan case paradigm. Syntactically, it encodes the subject argument, the entity that performs the action or about which a predication is made. Morphologically, it corresponds to the bare stem, with no suffix added, a feature consistent with the language's broader isolating tendencies. Subject reference is frequently reinforced by a personal pronoun, with me attesting the first person and an the third.

The genitive is the most extensively documented case in the surviving corpus, a distribution that reflects the overwhelmingly funerary and dedicatory character of the ancient Etruscan epigraphy, in which the identification of an object's owner or a tomb's occupant is the primary communicative purpose. Semantically, the genitive covers specification, possession and quality, but its functional range extends considerably further through case syncretism: it absorbs both instrumental and pertinentive functions that in other languages receive dedicated morphological expression. Instrumental relations, including means, manner, and agentive roles in passive constructions, are encoded through what may be termed a genitive of means, where the genitive specifies the medium of the offering. Pertinentive relations of topic and reference, which answer the question regarding whom, are similarly subsumed within the genitive, disambiguated through context and constituent order rather than through a distinct suffix.

The relational genitive constitutes a morphologically separate case within the same general possessive domain, distinguished by its expression of inherent relational bonds, filiation, kinship, and sacred dedication, as opposed to contingent ownership. Its archaic ending -ia / -iia, attested in the earliest inscriptions of the seventh and sixth centuries BCE, stabilises in the classical period as -al / -ial. Professor Massimo Pittau has proposed that the geminate spelling -iia marks prosodic prominence on that syllable. In the late phase of the language, the suffix undergoes erosion in group-declension contexts, leaving the relational value unmarked. The case likely originated as a derivational suffix generating relational adjectives, a category subsequently reanalysed and grammaticalised as a distinct case ending, a trajectory paralleled in dedicatory genitive systems elsewhere in ancient Mediterranean epigraphy, where filiation and divine dedication occupy a single morphological slot.

The dative encodes the indirect object and benefactive argument, identifying the participant toward whom an action is directed or for whose benefit or detriment it is performed. A notable feature of ancient Etruscan dative usage, which Neo-Etruscan fully inherited, is its extension to agentive function in passive and ergative-like constructions, as in clensi ("by/for the son"), which may preserve evidence of an earlier stage in which the categories of beneficiary and agent were not yet morphologically differentiated. This overlap between dative and agentive readings, functions that in Indo-European languages are typically distributed across the instrumental or ablative, is consistent with Etruscan's non-Indo-European typological character.

The accusative encodes the direct object, that is, the primary undergoer of the verbal action. Its functional range extends to directional motion and temporal duration. The accusative suffix -m is comparatively rare in the attested corpus, a distributional fact that admits two non-exclusive explanations: regular phonological reduction in later inscriptions, and the pragmatic sufficiency of zero-marking in short dedicatory texts where the patient argument is recoverable from context.

The vocative is the case of direct address and invocation. Unlike other cases, it plays no syntactic role within the proposition but serves a purely pragmatic, interactional function. Distinct vocative forms are poorly attested in Etruscan, which is readily explained by the nature of the corpus: funerary and votive inscriptions characteristically speak about a deity or the deceased in the third person rather than addressing them. In contexts where invocation does occur, most notably in the ritual formulae of the Liber Linteus, the vocative form is formally indistinguishable from the nominative, suggesting that Etruscan did not develop a morphologically autonomous vocative, a pattern shared by numerous languages across typological families.

The ablative expresses separative, ablative-source, causal, and limiting relations, specifying the literal or figurative point of departure of an event or state. The Etruscan ablative suffix -le / -ale additionally absorbs part of the pertinentive function: expressions of scope and limitation that in richer case systems occupy a dedicated slot are in Etruscan assigned to the ablative when they involve a relation of distancing or delimitation, as evidenced by Arathiale ziχuχe ("drawn by Arunte"), where the ablative marks the agent as an originating source. The conflation of separative and agentive-instrumental readings within a single case form is a well-documented outcome of case inventory reduction and has parallels across unrelated language families.

The locative specifies the spatial or temporal locus of a situation, encoding the place where an event occurs or an entity is situated. The Etruscan locative suffix -thi / -ithi is well represented in the corpus. The case shows a productive extension into temporal semantics, particularly in ritual calendar contexts where month and festival names appear in the locative to denote the occasion of a prescribed rite, as in acale ("in June") and celi ("in September"). This semantic broadening from purely spatial to spatio-temporal reference is characteristic of older case systems prior to the grammaticalisation of dedicated temporal cases or the replacement of case morphology by prepositional and adverbial constructions.
