The investigation centers on the unexpected ABA patterns exhibited by Icelandic singular noun inflections, which deviate from the anticipated syncretic behavior typically observed across languages. This research addresses a notable gap in the literature regarding Icelandic morphology, particularly the challenge of deriving pure ABA patterns within the framework of nanosyntax. While traditional theories suggest that syncretism should follow a predictable hierarchy (accusative < genitive < dative), the Icelandic instances of ermi and drottning reveal that such patterns cannot be derived under current nanosyntactic models. The significance of this work lies in its potential to reshape our understanding of morphological structures and their syntactic underpinnings.

The methodology employs a nanosyntactic approach, utilizing a detailed lexicalization algorithm that builds on unary features within syntactic terminals. The analysis begins with the decomposition of case features into cumulative structures, as proposed by Caha, and examines the lexical entries for the relevant morphemes. The researchers systematically explore the derivation of the problematic i/ar/i pattern, demonstrating how the requirements for structural identity in lexicalization lead to the conclusion that pure ABA patterns cannot be achieved. The use of evacuation movements, which allow for last-resort attempts to rescue lexicalization, is central to this exploration. By meticulously tracing the derivational steps, the researchers reveal the inherent limitations of the nanosyntactic framework in accounting for these Icelandic paradigms.

Key findings indicate that while pure ABA patterns are unattainable, a subtype of ABA-like pattern termed “protruding ABA” can be derived. This pattern, exemplified by the noun stað, features a bare root alternating with a suffixed form (Root / Root-x / Root). The researchers establish that the protruding ABA pattern aligns with the principles of nanosyntax and can be realized without altering the universal functional sequence of case hierarchies. The analysis further distinguishes between root-protruding and suffix-protruding ABAs, clarifying that the latter remains underivable within the current framework. This nuanced understanding of Icelandic morphology is bolstered by the introduction of “Blixemes,” which encapsulate the complexities of evacuation movements within lexical entries.

The broader implications of this research extend to adjacent fields such as computational linguistics and language technology, where understanding the intricacies of morphological patterns is crucial for developing accurate models of language processing. By elucidating the conditions under which protruding ABAs can occur, this work not only enhances our theoretical understanding of nanosyntax but also informs the design of more sophisticated morphological analyzers and parsers. The findings challenge existing assumptions about inflectional patterns and invite further exploration into the interplay between syntax and morphology, ultimately contributing to a richer comprehension of linguistic structure across languages.
