Bilingual Complex Abstract Lexical Structure and Its Relevance to Interlanguage Studies

This study adopts two assumptions about abstract lexical structure. One is that structure modular: information organized into subsystems pointing to different levels of linguistic structure, and parts can be split recombined. The other concerns the sources morphemes actually occurring in surface strings. As commonly recognized, contains three levels: lexical-conceptual predicate-argument morphological realization patterns. argues becomes “complex” because bilingual mental lexicon lemmas (i.e., entries lexemes) from sources, such as learners’ first language, their target interlanguage. By adopting a multi-layered speech production model (Levelt, 1989; Myers-Scotton & Jake, 2001; Wei, 2002, 2015, 2020), it further types are accessed at language production, resulting degrees learning difficulty (an implicational hierarchy second morpheme acquisition) learner errors interlanguage production. typical instances for collected performance by adult learners with various backgrounds. aims explore nature mechanisms development.
