ominaispiirteisiin

Ominaispiirteisiin is the illative plural form in Finnish related to the noun phrase ominaisuuspiirre, meaning features or characteristics. In practice, the form denotes movement toward or reference to a set of characteristics within a discussion or analysis. It is most common in formal or technical writing, such as scientific, linguistic, or philosophical texts, where researchers describe properties of a phenomenon or category and discuss entering the domain of those features.

Etymology and form: The term combines ominaisuus (property, feature) and piirre (trait, characteristic) to form ominaispiirre, pluralized as ominaispiirteet (features). The illative plural suffix -iin yields ominaispiirteisiin, indicating “into the features” or “to the characteristics.” The spelling variant ominaispiirteisiin appears in some texts, but the standard illative plural is ominaispiirteisiin.

Usage notes: Ominaispiirteisiin is used when the sentence requires illative case to express direction or scope into a set of features. It often occurs with verbs that introduce discussion, analysis, or comparison, such as keskitytään, viitataan, or tutkitaan, and with phrases describing relationships to features (ominaisuuksiin liittyvät, ominaispiirteisiin liittyvät). It is less common in everyday speech and more typical in scholarly writing.
