Fallvergleichs

Fallvergleichs is a term used in linguistics to describe the systematic comparison of grammatical case systems across languages or dialects. It encompasses the analysis of how nouns, pronouns, adjectives, and sometimes verbs mark and interact with syntactic roles such as subject, object, possessor, or oblique arguments, and how these usages vary over time or between languages.

In typological linguistics, Fallvergleichs investigates typologies of case systems and their distributions, such as nominative-accusative versus ergative-absolutive alignment. It also documents the inventory of cases across languages and examines correspondences between cases in related languages, along with their functional overlaps and distinctions.

Methodologically, Fallvergleichs draws on descriptive grammars, corpora, and historical records. Researchers compare case forms and functions, observe morphosyntactic patterns, and often construct cross-linguistic mappings or typological profiles. Quantitative and qualitative analyses may be combined to assess contact-induced change, syncretism, or semantic shifts of case meaning.

Applications of Fallvergleichs include language classification and typology, historical reconstruction, and the study of language change. It also informs language description, teaching, and natural language processing by clarifying how case systems encode grammatical relations and argument structure.

Examples across languages illustrate the range of systems: German uses four cases (nominative, accusative, dative, genitive) with role-sensitive morphology; Latin has six to seven cases; Finnish features an extensive case inventory; Turkish relies on suffixal cases; English largely reduced its case system to pronoun forms. Limitations arise from languages with little or no overt case marking and from polyfunctional or diachronically shifting cases. See also morphosyntax, typology, and nominal inflection.
