An Autistic “Linguatype”? Neologisms, New Words, and New Insights

In this commentary, we present new ideas about autistic neologisms. This essay has two primary goals. First, we argue that an autistic predilection to form neologisms generates intriguing new hypotheses about language in autism, including the possibility that a tendency to use neologisms could be a featural element of an autistic "linguatype" (as in "phenotype"). Second, we suggest that the study of neologism meaning, form, and use can yield insights about a specific speaker and about autistic language, generally. To support both aims, we present the largest collection to date of autistic neologisms. We supply an initial framework for considering and analyzing them, and we apply this framework to some of our collected examples, showing how individual neologisms can offer insights about their creators. Importantly, we suggest that neologism creation may sometimes signify linguistic giftedness, pushing back against traditional notions suggesting autistic neologisms are always evidence of language deficit. We hope this exercise will convince our community that autistic neologisms are deserving of more scientific attention and study. More broadly, by demonstrating the potential value of one feature of autistic language, we aspire to advance collective appreciation for the complexity of autistic language and thought.
