barter

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

  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 本词

  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。

• barter 本词

  A specific economic term for trading goods or services directly, with no money involved; typically used for commodities at markets, more formal and trade-related in register.

Swap and barter both name trading one thing for another. Swap is general and informal: it can involve anything, from seats to stories, and does not exclude money. Barter is an economic term for trading goods or services directly, with no money, typically for commodities.

两词都表示“互相交换”，但语气和场合不同：swap 是日常口语用词，泛指用一件东西换另一件东西，不限定是物品还是服务；barter 则专指不使用货币、以物易物的交易方式，常见于集市或经济史语境，语气更正式、更偏经济色彩。
