Kertymänominin

Kertymänominin is a theoretical term used in linguistics to describe a pattern of nominal inflection in which a single noun progressively accumulates a chain of affixes that fuse multiple grammatical meanings. The concept is applied in discussions of languages with highly complex nominal morphology and is not tied to a specific, well-documented language.

Etymology and usage: The term combines Finnish kertymä, meaning “accumulation” or “pile,” with a suffix-inspired element linked to nominal classification or nominals in the proposed framework. It serves as a label for the process of building up a nominal form through successive morphemes rather than through separate function words or independent phrases.

Mechanism and typology: In kertymänominin systems, a base noun can receive a sequence of agglutinative affixes. Each morpheme conveys a discrete category, such as number, case, definiteness, animacy, evidentiality, or mood. The order of affixes is typically fixed, and phonological adjustments like vowel harmony or consonant mutation may accompany the addition of morphemes. In some variants, the entire chain is required in certain syntactic environments; in others, morpheme choice is constrained by context or discourse.

Illustrative notes: Researchers may present constructed examples illustrating how a base noun N0 expands to forms like N0-PL-DEF-ERG-PAST-EVID, with each segment matching a specific grammatical function. These examples are synthetic and intended to illuminate the potential limits and trade-offs of heavy nominal morphology.

Significance: Kertymänominin provides a framework for analyzing languages that fuse multiple grammatical categories into a single nominal word, highlighting the balance between word length, information density, and syntactic flexibility. It remains a theoretical construct rather than a universally attested category.
