Words in their practical usage may not conform to the definitions or differentiations listed in dictionaries. With Yahoo American and Taiwanese stock market reports as situations, this study finds that in the context of /__/% (or sometimes / /百分比 in Chinese) in both situations, 9 English rise-similar words, 8 Chinese漲-similar words are found to be utilized as variants of rise and漲 respectively. (See Appendix 1 for Pin Yin and meaning of each Chinese word) Concerning the variants of the English fall and Chinese跌, 17 English words and 16 Chinese words are found to be applied. The 9 English rise-similar words and 17 fall-similar words, although not regarded as synonyms by dictionaries, are used in the same context. In terms of potency dimension or semantic range, the difference among the 8 Chinese 漲-similar words and 16 跌-similar words is more distinct. It is difficult, therefore, to translate each of the 9 English rise and 17 fall similar words into its Chinese counterpart.
