aikuisuudeksi

Aikuisuudeksi is a Finnish grammatical form, specifically the translative case of the noun aikuisuus, meaning adulthood. It denotes a change of state into adulthood and is used to discuss maturation as a concept or processes that result in the state of being an adult. In everyday speech this form is uncommon; speakers typically express the idea with aikuiseksi or with verb phrases such as tulla aikuiseksi or kasvaa aikuiseksi, depending on the context.

Morphology and etymology: aikuisuudeksi is formed from aikuisuus, the noun for adulthood, plus the translative ending that denotes a change into a state. The translative in Finnish marks movement toward or transformation into a new condition, and aikuisuudeksi literally conveys “into adulthood.” The form is most often encountered in linguistic descriptions, academic writing, or theoretical discussions of development and adulthood, rather than in casual conversation.

Usage and context: aikuisuudeksi is used when the focus is the abstract state of adulthood rather than a specific person becoming an adult. It is common in explanations of lifespan development, social concepts of adulthood, or analyses of maturation where the transition is described as a change into the state of adulthood. In practical terms, Finnish speakers will usually choose aikuiseksi or a verb phrase like tulla aikuiseksi to convey the same idea more naturally in everyday language.

Related terms include aikuisuus (adulthood) and aikuinen/aikuinen (adult), as well as common constructions such as tulla aikuiseksi or kasvaa aikuiseksi to express the developmental transition in more typical language.
