Let check the 演绎
Definition of 演绎:(I don't have official Chinese dictionary on hand so I used my common sense)
- verb. Acting, Show
- noun. the process of getting a conclusion by logical reasoning.(as poopsed to 'sum up')
Let be aware of the history of word'演绎'. For the English-Chinese translation experts(around the 1900s), using the '演绎' was the reasonable choice at that time.
And since it's like more than 100 years. I believe nobody would remember who firstly use this word. It's naturally used because its meaning of so close(or even the same) to "deduction".
The same logic could be applied to "米国"(Japanese) and "USA"(English). No one ever remembers who created "米国"
