käsitteisiin

Käsitteisiin is the illative plural form of the Finnish noun käsitteet, meaning concepts or notions. In Finnish grammar, the illative case expresses direction toward or into something, and the plural illative is used when referring to more than one concept. Therefore käsitteisiin translates roughly as “to the concepts” or “into the concepts,” depending on the context.

Morphology and formation: The form is derived from the plural stem käsitteet by adding the illative plural suffix -eisiin. This suffix is part of the broader illative system in Finnish and involves vowel harmony; the resulting word is spelled käsitteisiin. The corresponding singular illative is käsitteeseen, while the plural nominative is käsitteet.

Usage: Käsitteisiin is commonly found in academic, philosophical, or theoretical writing when discussing groups of ideas or constructs. It can appear as a direct object or as part of a larger predicate, often in phrases such as käsitteisiin liittyviä teoreettisia kysymyksiä (“theoretical questions related to the concepts”) or tutkitaan käsitteisiin liittyviä ilmiöitä (“we study phenomena related to the concepts”). The illative plural helps signal movement into or consideration of a set of ideas rather than a single notion.

Notes: Finnish noun cases, including the illative plural, require attention to stem changes and vowel harmony. Words like käsitteisiin illustrate how plural forms interact with case endings to express nuanced relational meaning in Finnish.
