The semantic structure of animal and emotion terms was here explored. In Study one, Chinese‐English bilinguals and monolingual English and Chinese speakers supplied similarity estimations. Those, once assayed with correspondence analysis, supplied a multidimensional representation of the semantic structure of animal terms; with the greatest similarity level noted between two bilingual structures. In Study two, a within subjects design was used and the participants assessed levels of similarity between pairs of emotion terms. The greatest level of similarity was recorded between the bilingual estimations supplied in English and the monolingual English ones. The aggregated findings have shown that the bilingual semantic structures are dynamic, potentially due to the constant interaction between two languages, which in consequence may induce creation of semantic interlanguage.
