Alaikäiseksi

Alaikäiseksi is a translative form of the Finnish adjective alaikäinen (underage). It marks a change of state or a designation of status as being a minor. The translative case -ksi expresses transformation, so alaikäiseksi is used in sentences that describe becoming or being declared underage, typically in formal or legal language.

In everyday Finnish, people under 18 are simply described as alaikäiset, but alaikäiseksi appears mainly in official contexts. Phrases such as todeta alaikäiseksi (to be deemed a minor) or määrätä alaikäiseksi (to designate as a minor) occur in guardianship, child protection, family law, and juvenile justice settings. The term emphasizes legal status rather than a casual description of age.

Legal context and implications: Finland’s age of majority is 18. Minors generally have limited legal capacity and may require guardianship or parental consent for certain actions. The use of alaikäiseksi is common when discussing procedures that determine or confirm a person’s minor status within these frameworks.
