misensuffixi

Misensuffixi is a term used in linguistic description to refer to the misapplication of suffixes during word formation. It describes cases in which a suffix with a defined semantic or grammatical function is attached to a base where that function is inappropriate, unlikely, or nonproductive. The result is a word that may be nonstandard, ambiguous, or difficult to parse, and that can shed light on how speakers organize morpheme inventory and productive suffixation.

Etymology and scope: the word is a blend built from the prefix mis- (wrong) and suffixi (a pluralized reference to suffixes). It is not a widely standardized term across all languages, but appears in discussions of error typology, language change, and second-language morphology. Researchers use misensuffixi to categorize and analyze deviations from expected affixation patterns, whether arising from learner transfer, language contact, or internal reanalysis.

Mechanisms: several factors contribute to misensuffixi. semantic mismatch occurs when a suffix denotes a meaning that does not align with the base’s lexical category. analogy can extend suffix use beyond its established domain. morphophonemic constraints or phonotactic pressures can push speakers to apply a suffix in unfamiliar contexts. misensuffixi can be transient, arising in interlanguage stages, or more stable in creoles, pidgins, or heavily contact-induced varieties.

Significance: studying misensuffixi helps linguists understand the boundaries of suffix productivity, the role of morphology in meaning, and how speakers resolve or regularize irregular affixation under pressure from other languages or dialects.
