sekamuotoisiin

Sekamuotoisiin is a Finnish linguistic term referring to the illative plural form of the adjective sekamuotoinen, which translates roughly to “mixed-form” or “hybrid form.” The base concept describes forms that display characteristics of more than one morphological or syntactic category. In descriptions of Finnish morphology, sekamuotoisiin denotes how such mixed forms are inflected in the illative case when the referent is plural and the direction or destination is indicated.

In Finnish, adjectives decline to agree with the noun they modify, and their endings change according to case and number. The illative plural forms often end in -iin, -isiin, -eihin, or similar variants depending on the stem’s phonology and any assimilations. Therefore sekamuotoisiin explicitly marks “to the mixed forms” in plural and illative mood. The phenomenon is primarily of interest in linguistic analysis rather than in everyday language use, because sekamuotoiset forms are typically discussed in the context of morpho-syntactic typology, historical change, or study of dialectal variation.

Sekamuotoisiin can appear in discussions of how language contact, historical sound changes, or irregular inflection patterns yield forms that combine features from different paradigms. Researchers may cite sekamuotoisiin as evidence of transitional or hybrid morphologies, illustrating broader questions about how languages organize case, gender, and agreement.
