精准的汉语释义英语释义辨析义
exchange 的词源义是“act f reciprcal giving and receiving”。它是由前缀 ex- (ut) 和 change 组成，可以理解为“拿……出去换成……”，其基本义是 “交换” 。
在原始社会，人们 “物物交换”，交换自己所需要的物资。但是有时候受到用于交换的物资种类的限制，不得不寻找一种能够为交换双方都能够接受的物品，这种物品就是最原始的货币。随着商品生产和交易量逐渐增大，商人们为了谈生意就必须商定一个固定的地点定期会见，就产生了“交易所”。

ex- 意为“ut 向外”

这是特朗普和希拉里在2016年竞选美国总统时的情形。据说这是美国史上最没底线的总统大选辩论。Why? 因为Trump and Clintn exchanged heavily in persnal attacks.
exchange的意义由交换具体的人或物到交换抽象的东西如思想或信息的转变。如果双方心平气和地交换思想或信息，可称为“交流”。如果双方怒气冲冲地交换的内容是人身攻击 (persnal attacks)，严肃的说法是“争论”，通俗的说法是“互撕”。
