vajavaisen

Vajavaisen is the genitive singular form of the Finnish adjective vajavainen, which denotes deficiency, insufficiency, or fragility. Vajavainen describes something not complete, adequate, or robust—such as resources, conditions, structures, or a person’s health or capacity. The word is common in formal and literary Finnish to characterize partial or precarious states.

Vajavaisen is used when the adjective modifies a noun in the genitive case, for example vajavaisen talouden tilanne (the situation of a fragile economy) or vajaisen henkilön asema (the position of a frail person). In everyday language, the sense covers economic, logistical, health, or informational deficiencies.

Synonyms include puutteellinen, heikko, riittämätön; antonyms include riittävä, täydellinen, vahva. The term appears in official reports, academic writing, and prose to express insufficiency or fragility. Etymology: vajavaisen derives from vajaa- plus the adjectival suffix -inen, with vajaa meaning "lacking" or "deficient." Related forms include vajavuus (deficiency) and vajavaisesti (deficiently).
