Contrastive Analysis of Japanese Particles Ga, Ni, O in the Learner's Composition Corpus in Bosnia and HerzegovinaMršo, Lamija (Avtor) Moritoki Škof, Nagisa (Mentor) Japanese LanguageLanguage AcquisitionError AnalysisLearner CorpusCase-Marking ParticlesDue to fundamental structural differences between Japanese and the Bosnian language, interference often occurs when Bosnian learners acquire Japanese case-marking particles. While Bosnian relies on inflectional suffixes to express grammatical categories and syntactic relations, Japanese uses uninflected particles such as ga, ni, and o. The multifunctionality of these particles, together with the topic–subject distinction seen in Japanese, frequently leads to confusion and misuse by Bosnian learners. The purpose of this paper is to identify grammatical errors resulting from negative language transfer through a qualitative corpus analysis. The study focuses on three Japanese particles ga, ni, and o, and aims to categorize learners’ errors and recurring patterns of misuse. The corpus consists of essays written by Bosnian native speakers learning Japanese as a foreign language. The findings also raise questions about the adequacy of grammatical explanations in textbooks commonly used in foreign language classrooms, suggesting that overgeneralization of case-particle rules may contribute to learner misunderstanding and persistent errors.[L.
