täydenn
Täydenn is a term used in Finnish linguistics to denote the verb stem associated with the sense of completing, filling in, or supplementing. In this usage, täydenn is not treated as an independent word you would find in everyday Finnish; rather, it is a morphosyntactic label applied to the core stem that underlies related verbs in the family that express the idea of making something complete or fuller. The concept is mainly of interest in grammar and etymology, where analysts examine how a common stem combines with person endings, numbers, moods, and other affixes to yield full verb forms and related derivatives.
Etymology and relation to other forms: Täydenn is connected to the semantic field of fullness and completion.
Usage and relevance: In practical Finnish, speakers would use concrete lexical items rather than the abstract
