Kleanthes K. Grohmann

Grohmann has authored, co-authored and co-edited works focusing on biolinguistics, psycholinguistics and socio-syntax. His 2003 book Prolific Domains: On the Anti-locality of Movement Dependencies explored anti-locality, an approach to syntactic computation and clause structure, introducing domains to restrict movement and offering a unified account of standard and anti-locality across clauses. In her review for the Language, Asya Pereltsvaig commented: "The book is clearly written and well argued. In addition to its contribution as a research monograph, it can be used as a text for an advanced undergraduate or graduate syntax course."^[8]

In 2013, Grohmann co-edited The Cambridge Handbook of Biolinguistics with Cedric Boeckx, exploring language development, evolution, and neuroscience, covering topics such as the language instinct, critical period hypothesis, and bilingualism. He also published a textbook, Understanding Minimalism alongside Norbert Hornstein and Jairo Nunesa, which introduces minimalist grammar, contrasting it with Government and Binding analyses. Mary Aizawa Kato remarked, "The book is highly recommended for all students of natural language syntax and generativists in particular."^[9]

Grohmann researched biolinguistics throughout his career. He outlined foundational questions in biolinguistics, distinguishing it from generative grammar, and proposed a research agenda on language pathology in comparative biolinguistics.^[10] With Maria Kambanaros, Evelina Leivada, Natalia Pavlou, Charley Rowe, and other students, postdocs, and colleagues from the CAT Lab, he explored language development in Cypriot Greek, introducing "bi-x" with emphasis on "(discrete) bilectalism" and the Socio-Syntax of Development Hypothesis to understand the connection between biolinguistic implications and clitic placement acquisition.^[11]

Grohmann's work on psycholinguistics encompassed language development and performance, particularly in children. In a 2014 study with Marina Varnava, he investigated how Cypriot Greek-speaking children aged 4 to 9 acquire the interpretation of wh-questions, revealing developmental discrepancies in a diglossic environment.^[12]

In joint work with Maria Kambanaros, Grohmann also looked into how children with specific language impairment (SLI) use general all-purpose (GAP) verbs as a sign of immature language, emphasizing the distinction from light verbs in language development.^[13] Additionally, they examined the language performance of a child with 22q11 deletion syndrome at ages 6 and 10, revealing improved morphosyntactic abilities over time but no changes in nonverbal IQ or vocabulary.^[14]

Collaborating with Christiana Christodoulou, Grohmann analyzed subjunctive clause comprehension in Greek Cypriot bilectal children with Down syndrome, finding parallel performance with typically developing children and unaffected acquisition by linguistic differences.^[15]

Grohmann has investigated multilingualism and its impact on language acquisition. In joint research, he observed multilingual children with specific language impairment showing a consistent preference for retrieving nouns over verbs, suggesting a shared grammatical principle across languages.^[16] He also used cognates as an effective intervention for multilingual children with specific language impairment, resulting in significant improvement in English and cross-linguistic transfer effects to Bulgarian and Greek.^[17]

Grohmann and colleagues found executive control advantages in bilectal children (Cypriot Greek and Standard Modern Greek) over monolinguals, linked to working memory and inhibition, emerging after considering lower language proficiency.^[18]
