ytimä

Ytimä is a term used in a hypothetical linguistic framework to denote the central semantic unit of a word—the part that carries the core lexical meaning. In this framework, words are analyzed as comprising a ytima plus various affixes. The ytima determines the primary reference or concept, while derivational and grammatical affixes attach to it to modify meaning, part of speech, tense, number, or case.

Etymology: The term ytimä is a neologism built from Finnish ydin "core" and a nominalizing suffix -mä, invented to distinguish the core meaning from the surrounding morpho-syntactic material. It is not an established term in mainstream linguistics and remains primarily in theoretical or instructional use.

Applications and notes: Proponents suggest that identifying the ytima can help clarify how words derive related terms and how meaning shifts across inflection. Critics argue that the concept overlaps with the existing notion of the lexical root or stem and risks reifying abstract distinctions. In practice, ytimä is mainly found in pedagogical discussions or thought experiments rather than formal analyses.
