The errors of Persian language learners in using Japanese final particles “ne”, “yo” and “yone”

In Japanese conversation, the grammatical final particles, “yo”, “ne” and “yone” play an important role. So far, a lot of research has been done in relation to their functions, and the mistakes that language learners face when using them. This current research, with the purpose of something clarifying Persian language learner’s blind spots in learning these three final particles, investigated their role and functions in the sentence, then analyzed the answers of a test related to these three final particles which were obtained from 116 Iranian language learners and Japanese speakers. we determined the errors of the language learners in three different categories. In connection with the final particle “yo”, the majority of errors were about recognizing the function of “drawing attention”, “requiring awareness and recognition”, “emphasizing the will and desire”, “expressing satisfaction and agreement” and “requesting correction”; while associate with the final particle “ne”, most of the problems occurred in recognizing the functions of “expressing agreement and consensus”, “self-emphasis” and “demanding apparent satisfaction” was the greatest problem and the utmost errors related to “yone” was recognizing “receiving confirmation for a presupposition” and “providing an explanation with the audience”. Afterward, the source of these errors has been investigated and divided into four propellants“lack of final particles modality functions recongnition”,“insufficient explanations in educational resources and errors caused by educational procedures”, “Multiple and similar functions of this final particles” and “The uniqueness of final particles features”which have been analyzed during this particle and then presented solutions for how to teach them.
