itsekalvoihin

Itsekalvoihin is a Finnish inflected form derived from the compound noun itsekalvo, which literally means “self-membrane.” The form itsekalvoihin is the illative plural: it translates roughly to “into/onto the self-membranes.” This construction combines the prefix itse- (self) with kalvo (membrane) and the plural illative suffix -ihin, a common Finnish way to indicate motion toward a plural noun.

In use, itsekalvoihin appears mainly in specialized or technical contexts, such as discussions of cellular biology, bioengineering, or materials science where membranes produced by a system itself are contrasted with external or artificial membranes. Because itsekalvo is not a everyday term in Finnish, its illative plural form itsekalvoihin is rarely encountered outside scholarly or speculative writing. When it does appear, it typically functions as a direct object or a target of verbs that express movement toward or interaction with membranes, for example in phrases describing interactions with or localization to self-produced membranes.

Etymologically, the word showcases Finnish morphology: a compound noun formed from itse- plus kalvo, combined with the illative plural suffix -ihin. Its usage highlights how Finnish can create precise technical terms through compounding and case endings, even for concepts that do not have a widely established everyday presence.
