【问】 notion (概念)与concept，conception有何区别?

【答】 concept与conception的区别，见concept/conception。notion和concept一样，也可用于表示普遍的、被广泛接受的概念，例如：

The notion that the world was round had been conceived centruries before.

关于地球是圆的概念，在许多世纪以前就被接受了。

但是，notion常常在idea的基本含义上附加模糊不清、无理论根据、不切实际、瞬时间产生等

含义：

他的脑海充满了奇怪的想法。

2. I never knew anyone with such odd notions. (FWF)

我从未认识任何人，具有这样的奇思妙想。
