exchange

Compared meaning: giving one thing to get another (noun/verb).

比较义项：用一样东西换取另一样东西（exchange 为名词，barter 为动词）。

• exchange 本词

  A general noun for giving one thing and getting another back; it does not say whether money is involved, so it fits casual or sentimental swaps as well as trade.

  泛指“给出一样东西并换回另一样东西”的名词，不说明是否涉及货币，因此既可用于随意的、带感情色彩的互换，也可用于交易。

  The exchange of gifts is a holiday tradition in many families.

  在许多家庭中，互赠礼物是一项节日传统。

• barter

  A verb for trading goods or services directly without using money; it is more specific and typically used in market, economic or historical contexts, not for casual gift-giving.

  指不使用货币、直接用物品或服务进行交易的动词，语义更具体，通常用于市场、经济或历史语境，不用于随意的礼物互赠。

  The farmers used to barter vegetables for eggs at the market.

  农民们过去常在市场上用蔬菜换鸡蛋。

Exchange and barter both describe giving one thing to get another. Exchange, a noun here, is general: it does not say if money is involved, fitting casual swaps or trade. Barter, a verb here, means trading goods or services directly, without money, in market contexts.

这两个词都表示“拿一样东西换另一样东西”，但用法不同：exchange（这里作名词）泛指互相交换的行为，不强调是否涉及货币，也不限定交换的是什么；barter（动词）特指不使用货币、直接以物易物或以服务换物，语气更具体，常用于经济、历史或市场交易的语境。这里不比较 exchange 作动词或指“交易所”等其他用法。

Compared meaning: to trade one thing for another (verb).

比较义项：兑换／交换一物换取另一物（动词）。

• change

  Typically describes converting one form of money or item directly into another, often with "into" or "for"; usually one-directional, not necessarily reciprocal between two people.

  通常指把一种货币或物品直接换成另一种，常与“into”或“for”搭配；一般是单方面的转换，不一定是双方之间的互换。

  The machine will change your coins into bills.

  这台机器会把你的硬币兑换成纸币。

• exchange 本词

  Emphasizes a mutual give-and-take between two people or parties, often followed by "with"; used for reciprocal actions like gifts, contacts, or ideas, as well as formal currency exchange.

  强调双方之间的互相给予和接收，常与“with”搭配；用于礼物、联系方式、意见等的互换，也可指正式的货币兑换。

  They exchanged phone numbers with each other after the meeting.

  会议结束后，他们互相交换了电话号码。

Change and exchange both mean to trade one thing for another. Change usually means converting one form of money or item into another, often with 'into' or 'for', not necessarily mutual. Exchange means a mutual give-and-take between two people, often with 'with', for gifts.

change 与 exchange 在“兑换／交换”这一义项上意思相近，但 change 更强调把一种东西换成另一种，语气较随意，常见于货币或日常场景；exchange 更强调双方之间的互相给予和接收，语气较正式。这里不比较 change 的“改变、改换”（如 change one's mind）等其他义项，也不比较 exchange 的“交流意见”等其他义项。
