kyllästyydellä

Kyllästyydellä is a Finnish grammatical form that appears in linguistic discussions rather than ordinary speech. It represents an adessive form derived from the root related to the verb kyllästyä, meaning to become bored. In this sense, kyllästyydellä can be described as the adessive case of a nominalized concept connected to boredom or weariness, i.e., “with boredom” or “by boredom.” The construction is relatively rare and is mainly used to illustrate how Finnish expresses means or circumstance via the adessive rather than a dedicated instrumental case.

Etymology and morphology: The form builds on the verb stem kyllästy-, related to the noun notion of boredom (kyllästytys/kyllästyminen) and adds the adessive suffix -llä. Finnish often uses the adessive to indicate means or circumstance, including abstract states such as boredom, when a more direct instrumental is not available.

Usage: Kyllästyydellä is primarily encountered in linguistic analyses, grammars, and stylistic discussions about Finnish case usage. It is not common in everyday spoken Finnish, where speakers would typically use other constructions to express the idea of performing or experiencing something under a state of boredom.
