deriveatteja
Deriveatteja is a term used in theoretical linguistics to denote a subclass of derived word forms that are attested in corpora but whose derivational status is opaque or contested within standard morphological analysis. The label is applied to forms whose origin, productivity, or semantic relation to a base cannot be satisfactorily explained by routine derivational rules, and which typically require irregular, semi-productive, or language-specific processes to account for them.
Origin and etymology: The term is a neologism formed by combining derive with a plural-suffix-like element -atteja.
Definition and scope: A deriveatteja form is an attested word form that appears to be derived from
Methodology: Researchers identify candidate deriveatteja by corpus analysis, historical etymology, and morphophonemic reconstruction. Distinguishing them from
Examples and significance: In some languages, certain agentive or denominal nouns exhibit irregular derivations that resist
