arXiv:2507.21556v3 Announce Type: replace Abstract: The cognitive reality of irregular morphological patterns has been debated for decades: do speakers extend them to novel forms, or are they lexical artifacts? A neural network trained on distributional input offers a learnability test: if it recovers the pattern, the pattern is learnable from input statistics alone. We apply this test to the Spanish L-shaped morphome, where the first-person singular indicative stem appears in every present subjunctive cell despite lacking apparent phonological or semantic motivation. We further ask whether th
This paper leverages advanced neural networks, specifically Transformers, to explore long-standing debates in cognitive linguistics regarding morphological learning, a testament to AI's growing analytical capabilities in complex human cognition.
A strategic reader should care because this research deepens understanding of how AI models learn and generalize linguistic patterns, which is critical for developing more robust and human-like AI systems capable of complex reasoning and interaction.
This research shifts the understanding of linguistic learnability by demonstrating that complex, seemingly irregular patterns can be identified by neural networks based on distributional input, suggesting these patterns might be less 'special' than previously thought.

Further research will explore other linguistic irregularities and their learnability by AI models, contributing to a unified theory of language acquisition.
Improved AI understanding of morphological patterns could lead to more nuanced and accurate machine translation and natural language generation, especially for highly inflected languages.
As AI models better mimic human language acquisition, this could open new pathways for AI-driven education and personalized language learning, optimizing pedagogical approaches based on empirical learnability.
