Under the multiple cultural backgrounds of growth, children from Chinese-Japanese transnational families need to learn various languages as daily communicative tools. When they communicate with non-multilinguistic speakers, there exists a varying degree of “errors” of performance. These “errors” of performance do not entirely reflect in the sense of the linguistic constitution, such as grammar and spelling. In other words, albeit multilinguistic speakers sophisticatedly master the linguistic structure, they sometimes “misuse” the language in individual situations anyhow. These “errors” of performance are often seen as inadequate competence and often be corrected by the surrounding circumstances. This paper will focus on the multilinguistic speakers’ “errors” of performance from the anthropological perspective. I will not search for the error from the grammatical structure point of view but shed some light on the questions below: for what kind of emotional purpose, and in what kind of context, multilinguistic speakers use the language in that way? Simultaneously, I will combine speakers’ explanations to discuss the rationality of the “errors” of performance.
