Käsittelysanan

Käsittelysana, whose genitive form is käsittelysanan, is a Finnish term that translates roughly to "processing word." It is not a standard grammatical category in Finnish, but is used in some linguistic and computational contexts to refer to a word that is the subject of processing or analysis. The exact meaning varies with the author and field. In linguistics, käsittelysana can denote a word that is the focus of an analysis step, such as morphological segmentation, syntactic tagging, or semantic interpretation. In information technology and natural language processing, the term is used informally to describe the word that a program will process as a target in a pipeline, for example during tokenization, lemmatization, or parsing. Because it is informal and context dependent, käsittelysana is not interchangeable with formal terms like lemma or word form, though it may be used as a rough surrogate in teaching materials or documentation.
