Lexical Variation in Early Language Acquisition: A Comparative Study

This study compares data from dialectlexicography and first language acquisition to explore the vulnerability to variation of acquired lexical items. Topics include lexical diversity, acquisition, and tools for analysis. The research investigates the origin and diversification of language through examples from German, Dutch, English, Frisian, and Swedish. Various lexical items are analyzed to understand acquisition patterns and frequency of production. Tools like COAVA are utilized for dialectlexicography and CHILDES for measuring lexical variation.
