Lexemesuch

Lexemesuch is a term used in linguistics and lexicography to denote a framework or system for organizing and querying lexemes—the canonical dictionary form of a word and its related inflected forms. In its broad sense, lexemesuch refers to both the data model and the tooling that connect lemmas, their inflectional paradigms, senses, etymologies, and semantic relations across languages.

A typical lexemesuch entry consists of: lemma, part of speech, inflectional paradigm, sense inventory with definitions and examples, etymology, semantic relations (synonyms, antonyms, hypernyms), cross-linguistic links, and sometimes frequency data. The system may support multiple scripts and languages and can be implemented as a relational database, a graph database, or an RDF/OWL ontology. This enables advanced queries such as retrieving all inflected forms of a lemma, filtering by semantic field, or finding cognate lemmas across related languages.

Applications of lexemesuch include lexicography, natural language processing pipelines, educational tools, and historical linguistics. It acts as a unifying layer between dictionaries, corpora, and lexical resources, facilitating lemmatization, morphological analysis, sense disambiguation, and cross-resource interoperability.

The concept appears in theoretical discussions and some open-source projects, where researchers envision lexemes as the primary unit of the lexicon and propose interoperable data schemas to support lexical queries across corpora and languages.
