accord

Compared meaning: a formal agreement (noun).

比较义项：正式协议（尤指国家或团体之间）（名词）。

• accord 本词

  Accord refers to a formal agreement reached through negotiation, often on political or diplomatic matters; it collocates with reach/sign an accord and sounds slightly less rigid than treaty.

  accord指经过谈判达成的正式协议，常用于政治或外交事务，常与reach/sign an accord搭配，语气比treaty略显不那么严格。

  The two countries finally reached a peace accord.

  两国终于达成了一项和平协定。

• treaty

  Treaty is the most formal and legally binding term, typically a written document between national governments that is signed and often ratified; it is the standard word for major international agreements.

  treaty是最正式、最具法律约束力的词，通常指国家政府之间签署、并常需批准的书面文件，是表示重大国际协议的标准用词。

  The two nations signed a treaty to end the war.

  两国签署了一项条约以结束战争。

• pact

  Pact is the broadest term, covering agreements between countries, groups, or even individuals; it can sound informal or personal, unlike the strictly international, legalistic tone of treaty.

  pact是最宽泛的词，可用于国家、团体甚至个人之间的约定，语气可以显得非正式或私人化，不同于treaty那种严格的国际性、法律性语气。

  The two neighbors made a pact to share garden tools.

  两位邻居达成约定，共用园艺工具。

These three mean a formal agreement, but scope and formality differ. Treaty is most formal, a legally binding document between governments. Accord is reached through negotiation, often political or diplomatic. Pact is broadest, for countries, groups, or individuals. Not compared: accord's harmony sense.

这三个词都指正式达成的协议，但正式程度和适用范围不同：treaty最正式、通常需要签署甚至批准，专指国家间的书面条约；accord次之，强调通过谈判达成一致，多用于政治或外交场合；pact最宽泛，既可指国家间的正式条约，也可指个人或团体间随意的约定。这里不比较accord表示“和谐、一致”的其他用法（如in accord with）。

Compared meaning: to agree with or match something (verb).

比较义项：与……一致，协调（动词）。

• accord 本词

  Accord is mostly used with 'with' to say that facts, statements, or actions match or are consistent with something else; formal, often written or legal.

  accord主要与with连用，表示事实、说法或行为与另一事物相符或一致；语气正式，常见于书面或法律语境。

  His explanation didn't accord with the evidence found at the scene.

  他的解释与现场发现的证据不一致。

• harmonize

  Harmonize means to make different things, such as sounds, colors, or opinions, blend together pleasingly or become consistent; often transitive, common in music and design.

  harmonize指让不同的事物（如声音、颜色或意见）搭配得悦耳或趋于一致，常作及物动词，多用于音乐和设计等语境。

  The decorator chose curtains that harmonize with the soft blue walls.

  室内设计师挑选的窗帘与柔和的蓝色墙壁很协调。

Accord and harmonize both mean to be consistent with something, but usage differs. Accord is used with 'with', for facts or actions matching something, often formal. Harmonize means making different things, like sounds or opinions, blend nicely. Not compared: accord as a noun for agreement.

这两个词都表示“与……一致、协调”，但accord强调事实、说法或行为客观上与另一事物相符，常用accord with结构，语气正式，多见于书面或法律语境；harmonize强调让不同的事物（声音、颜色、意见等）搭配得悦耳或趋于一致，也常作及物动词使用，多见于音乐、设计和政策统一等语境。这里不比较accord作名词表示“协议”的用法（如a peace accord）。
