One more messy bit: in English, nausea is the feeling in the body. In Chinese, 噁心 can mean that same body feeling, but it can also mean 'that's gross' about a person or an idea. English nausea does not do that second job by itself.

One more messy bit還有一個容易搞混的地方 : in English在英文裡 nausea nausea講的是 is the feeling in the body身體裡的那種感覺。 In Chinese中文的 「噁心」 噁心 can mean可以指 that same body feeling同樣那種身體感覺 but but 也 it can also mean可以拿來罵 'that's gross'很噁心、很討厭 about a person or an idea一個人或一個想法。 English nausea英文的 nausea does not do that second job自己並不會拿來做第二種用法 by itself。
