Työkykyynsä

Työkykyynsä is a Finnish grammatical form of the noun työkyky, meaning work capacity or the ability to work. The form combines the illative case, which expresses direction toward or into something (into one’s work capacity), with the third-person possessive suffix. In practice, työkykyynsä is used to talk about changes, effects, or actions directed at an individual’s own work capacity. The construction is common in formal or technical texts, such as health, rehabilitation, employment, and social protection contexts.

In usage, työkykyynsä typically appears in sentences that describe how illness, injury, or treatment affects a person’s capacity to work, or how measures aim to preserve or restore that capacity. It is distinct from kuten työntekijän työkykynsä, which refers to the person’s own work capacity as a possession in a more general sense (often with the genitive form työkykynsä). Because työkykyynsä centers on the direction toward the capacity, it is frequent in phrases about impacts, evaluations, or procedures related to one’s ability to work.

Common contexts include medical assessments, rehabilitation planning, vocational rehabilitation, and social insurance discussions where the focus is on how someone’s ability to work is influenced or addressed. For readers unfamiliar with Finnish grammar, the key idea is that työkykyynsä marks “to one’s work capacity” rather than simply stating possession of work capacity.
