heikkeneä

Heikkeneä is a Finnish verb form that appears as the infinitive of the intransitive verb meaning to become weaker or to deteriorate. In standard Finnish, the corresponding infinitive is usually heikentyä, and heikkeneä is considered a nonstandard, dialectal, or historical variant. The form is most often encountered in descriptions of regional speech, older texts, or language descriptions rather than in contemporary everyday Finnish.

The basic meaning of the verb is a change in state toward reduced strength, capacity, or condition. It is used to describe processes where conditions, health, performance, or structures lose vigor or stability over time. The action is intransitive, focusing on the subject’s own state rather than on something causing the change.

Morphology and usage notes: in standard Finnish, the related common verb is heikentyä. The present tense forms of the standard verb are used to express gradual decline or weakening, for example, Кunto heikkenee (the condition weakens). Because heikkeneä is nonstandard or dialectal, it is typically avoided in formal writing in favor of heikentyä. When encountered, it is often interpreted as referring to the same semantic field but with regional pronunciation or historical flavor.

Etymology: the word derives from the adjective heikko (weak) with a suffix pattern that forms intransitive verbs indicating a change of state. It is related to, and often compared with, the standard heikentyä and the parallel noun forms such as heikkeneminen or heikentyminen.
