Heikkouden

Heikkouden is the genitive form of the Finnish noun heikkous, meaning weakness or frailty. In Finnish, heikkous denotes a lack of strength, energy, or power. The base word heikkous comes from the adjective heikko (weak) with the abstract-noun suffix -us. The form heikkouden appears in phrases such as “heikkouden syyt” (causes of weakness) or “heikkouden tunne” (a feeling of weakness).

Usage and scope: Heikkous is used in medical, physical, and non-medical contexts. In health, it often refers to fatigue or generalized weakness and can accompany illness, malnutrition, sleep deprivation, or neuromuscular disorders. It can be acute or chronic. Metaphorically, it may describe vulnerabilities in systems, processes, or organizations, such as “heikkouden hallinta” (management of weaknesses). It contrasts with vahvuus (strength).

Examples and nuances: The term does not specify a diagnosis; clinicians typically name the underlying cause of weakness, such as anemia or thyroid disease. In everyday language, people speak of feeling weak after exertion or during illness. In literature, heikkous may also denote moral or psychological frailty. The genitive form heikkouden is mainly used to indicate possession or relation, e.g., “heikkouden vaikutus” (the effect of weakness).
