muuntoneutraalisena

Muuntoneutraalisena is a term used in theoretical linguistics to describe the neutralization of a feature during a transformation of a form. The word combines muunto (transformation or morphing) with neutraalisena (in a neutral form), conveying the idea that a feature loses its contrastive value as a result of a morphophonological or morphosyntactic rule. The term is not standardized across the literature and is found mainly in discussions of how transformations interact with feature specification.

Definition and scope: In analyses that track underlying representations and surface forms, muuntoneutraalisena denotes the outcome in which one or more phonological or grammatical features are set to a default, neutral value, so that otherwise distinct variants become indistinguishable in certain contexts. It is distinguished from general allomorphy by emphasizing the neutralization that occurs specifically through a transformation rather than through the selection among competing allomorphs.

Mechanisms and examples: Neutralization can arise from rules that suppress contrasts, such as consonant gradation, vowel harmony, or affix-triggered feature erasure. A surface example is that underlying forms converge to the same surface form under a transformation rule, because the targeted feature is neutralized during muunto neutraalisena. In formal models, this is often represented as an erasure or defaulting of the feature value during the transformation phase.

Relation and discussion: The concept relates to broader topics of neutralization in phonology, morphophonology, and feature theory. Critics may argue that muuntoneutraalisena can obscure distinctions that remain latent in underlying representations, while proponents view it as a useful shorthand for describing transformation-induced simplification.
