bargain

Compared meaning: an agreement between two sides (noun).

比较义项：交易，协定（达成的协议）（名词）。

• bargain 本词

  Bargain refers to an agreement reached after negotiating, especially over a price; it appears in the fixed phrase 'strike a bargain' and often implies one side got favorable terms.

  bargain 指经过讨价还价后达成的协议，尤其与价格有关，常见于固定搭配“strike a bargain”（达成协议），并往往暗示其中一方获得了有利条件。

  After some haggling, she struck a bargain with the vendor and paid half the original price.

  经过一番讨价还价，她和小贩达成了协议，只付了原价的一半。

• deal

  Deal is the everyday, general word for any agreement or transaction, business or personal, with no implication of negotiation over price; used in phrases like 'make a deal' or 'a business deal.'

  deal 是日常用语中泛指任何交易或约定的通用词，不论是商业上的还是私人之间的，不必然暗示价格上的讨价还价，常用于“make a deal”（达成协议）或“a business deal”（一笔生意）等表达。

  My brother and I made a deal: he does the dishes and I take out the trash.

  我和哥哥达成了一个约定：他洗碗，我倒垃圾。

Both are nouns for an agreement, but bargain implies negotiation. Bargain refers to an agreement reached after negotiating, especially over a price, often favoring one side. Deal is the everyday, general word for any agreement or transaction, with no negotiation implied.

这两个词都可以指双方达成的一项交易或约定，但语气和使用场合不同：bargain 更强调经过讨价还价、通常与价格有关而达成的约定，语气略带书面色彩；deal 则是日常口语中泛指的交易或约定，几乎可用于任何场合。这里不比较 bargain 的“廉价商品”义项，也不比较 deal 的“数量”义项。
