aiheeksi

aiheeksi is the translative form of the Finnish noun aihe, meaning a topic or subject. It is used to express turning something into a topic or designating it to be treated as such, for example in planning, discussion, or analysis. The form indicates a change of state or role, such as assigning something to be the topic of a discussion or study.

In practice, aiheeksi is often found with verbs like valita (to choose as), asettaa (to set as), or ottaa (to take up as). Examples include: Keskustelun aiheeksi valittiin kiertotalous. Tämän julkaisun aiheeksi valitsimme ilmastonmuutoksen. Koulutuksen ohjelmassa aiheeksi nostettiin vesihuolto. These constructions show how aiheeksi signals that the matter will be treated as the central topic.

Alohkaisen contrast, the essive form aiheena means “as a topic” in the sense of the topic that is being discussed or considered at the moment, as in Keskustelun aiheena oli ilmastonmuutos. The translative form and the essive form serve related but distinct functions: aiheeksi emphasizes designation or transformation into a topic, while aiheena emphasizes the topic in the ongoing discussion.

Etymologically, aiheeksi is formed from aihe plus the suffix -ksi, which denotes becoming or functioning as something. The term is common in written Finnish, especially in journalism, academic writing, and formal planning, and it coexists with other related forms such as aiheena and other grammatical cases of aihe.
