leksikko

Leksikko, in Finnish linguistic usage, refers to the lexicon or vocabulary of a language, dialect, or specialized domain. It is the structured inventory of lexical units that speakers use, including lemmas, inflected forms, senses, pronunciation, and typical collocations. While the English term is lexicon, leksikko is the Finnish equivalent and is widely used in Finnish-language linguistics, education, and lexicography.

A leksikko can be general, covering the entire vocabulary of a language, or specialized, focusing on a field such as medicine, law, technology, or a particular social register. It may also be learner-oriented, describing the set of words deemed essential for language learners. Leksikko entries can be descriptive, reflecting actual usage, or prescriptive, guiding which words learners should know in a given context.

Typical leksikko entries include the headword (lemma), part of speech, semantic senses, example sentences, pronunciation, morphological information, and sometimes synonyms, antonyms, or usage notes. In computational linguistics, a leksikko often serves as a lexicon for natural language processing systems, with entries enriched by features such as grammatical tags and, in advanced systems, semantic or frequency data.

The construction of a leksikko relies on corpus data and lexicographic theory, emphasizing clear sense distinctions, comprehensive coverage of relevant domains, and cross-references between related terms. Leksikko plays a central role in dictionaries, language teaching, translation, information retrieval, and NLP applications.
