Lim, Hye-Soon. 2002 Language Mixing in the Bilingual Child: A Case Study, The History of English, 13. This paper is to support the universality of language development through the analysis of language mixing in the bilingual child. In the bilingual development children have two distinct linguistic systems to which they are exposed. With two languages they employ language mixing either when they lack the lexical entry in the appropriate language or when the mixed entry is more salient to the child. When these mixes occur the structural consistency of the utterance is maintained depending on the situation. Their language mixing shows the competence to differentiate two linguistic systems. Key words: bilingual, mixing, objectification telegraphese, universality
