sufiksem

Sufiksem is a linguistic term used to describe the most productive class of suffixes in a language, particularly those that repeatedly derive new lexical items or grammatical forms from existing stems. In morphology and language typology, sufiksem is used to distinguish derivational suffixes with broad applicative potential from less productive inflectional endings.

Etymology and usage: The word is a recent neologism in scholarly literature and is not uniformly standardized across languages. It combines the concept of a suffix with a generic -sem ending to signify a category of suffixes, rather than a single morpheme.

Definition and criteria: A sufiksem is characterized by high productivity, semantic versatility, and cross-lexical applicability within a given language. It often yields distinct word classes (for example, nouns from verbs or adjectives from nouns) and tends to remain productive across historical stages. Distinctions are drawn between sufiksem and other morphological processes such as compounding or internal derivation via stem-change.

Cross-linguistic notes: Some languages with rich suffixal morphology display clear sufiksem patterns, but the label is not universally used. Researchers may identify sufiksem by corpus-based productivity tests, diachronic evidence, or descriptive data.

Examples (conceptual): In a hypothetical language, a suffix -ar might form agent nouns from a wide range of verbs, while -ism could derive abstract nouns from adjectives. These are representative patterns, not universal rules.
