murtumisiin

Murtumisiin is a Finnish grammatical form that appears in linguistic descriptions of the illative case. It represents a directional illative plural form, indicating movement toward or into fractures. The word is built from the stem related to the noun meaning fracture or breaking (such as murtuma or murtuminen) and a plural illative suffix, yielding a construction that roughly translates to “into fractures.”

In Finnish morphology, the illative marks direction toward something, and plurals are formed by adding appropriate suffixes to the stem. Murtumisiin is typically discussed in grammars and dictionaries as an example of how noun stems derived from -minen or related forms can take the illative plural suffix. Because it concerns a specialized grammatical phenomenon rather than everyday usage, murtumisiin is seldom found in ordinary speech or writing outside linguistic analysis.

Usage notes suggest that more common everyday equivalents for discussing fractures in plural terms are murtumiin (illative plural of murtuma) or other context-appropriate constructions, depending on whether the reference is to individual fractures or the process of fracturing. Murtumisiin thus serves primarily as a technical illustration of Finnish case and number interplay rather than as a frequently used lexical item.
