radikkelista

Radikkelista is a term used in some Nordic-language linguistic and natural language processing contexts to refer to a curated inventory of word roots (radices) extracted from a corpus or lexicon. The word combines a notion of root meaning with lista (list), effectively describing a “root list” that emphasizes base forms over inflected variants. In Finnish and related contexts, the concept is used to describe resources that facilitate morphological analysis and lexicon development.

A radikkelista typically includes entries that identify the base/root form of words, often accompanied by metadata such as part of speech, derivational relationships, frequency counts, and sometimes semantic information. It is distinguished from a simple lemma list by its focus on the minimal morpho-phonological units that underlie word formation, sometimes together with affix patterns or rules used to generate or analyze derived forms. Some implementations enrich the radikkelista with information about inflectional classes or derivational families to support language-specific morphology.

Radikkelistan are used within computational workflows such as lemmatization, stemming, morphological analysis, and lexicon construction for search systems and language models. They help organize linguistic data around roots to improve coverage of inflected forms and to support cross-linguistic or multilingual processing, though building a comprehensive radikkelista requires careful handling of homographs, irregular forms, and multiword roots.

Because the term is not widely standardized, definitions and contents of a radikkelista can vary between projects. See also morphology, stemming, lemmatization, lexicon.
