offer

Compared meaning: to give someone something they need (verb).

比较义项：给予，提供（某人所需之物）（动词）。

• provide

  The neutral, all-purpose choice for giving someone something needed, physical or abstract; fits almost any register and pairs naturally with abstract nouns like support, information or education.

  provide 是最中性、通用的词，指给予他人所需之物，可以是具体物品也可以是抽象事物；几乎适用于任何语域，也能与 support（支持）、information（信息）、education（教育）等抽象名词自然搭配。

  The counselor provides emotional support to students dealing with exam stress.

  这位辅导员为应对考试压力的学生提供情感支持。

• offer 本词

  Stresses that the thing is being presented for the other person to accept or decline; it does not guarantee the item is actually taken, unlike provide, render or supply.

  offer 强调把某物提出来，让对方自行选择接受或拒绝，并不保证对方真的会接受，这一点不同于 provide、render 或 supply。

  She offered him a ride home, but he decided to walk instead.

  她主动提出送他回家，但他还是决定走路回去。

• render

  Formal and rather stiff; typically used with abstract nouns like aid, service or a verdict rather than physical goods, and common in legal or professional writing.

  render 语气正式、较为生硬，通常与 aid（援助）、service（服务）、verdict（裁决）等抽象名词搭配，而不是具体物品，常见于法律或专业文书中。

  The court rendered its verdict in favor of the plaintiff after two days.

  法庭在两天后作出了有利于原告的裁决。

• supply

  Emphasizes giving a quantity of something, often material goods or a resource, on a regular or large-scale basis, more than a single act of giving.

  supply 强调持续或大批量地给予某种数量的东西，通常是物资或资源，而不只是一次性的给予行为。

  The reservoir supplies drinking water to three million people in the region.

  这座水库为该地区三百万人供应饮用水。

All four mean to give someone something needed. Provide is the neutral, all-purpose word. Offer stresses presenting something that may be accepted or refused. Render is formal, used with abstract nouns like aid. Supply stresses giving a quantity, often material goods, on a large scale.

这四个词在“提供、给予所需之物”这一义项上意思相近，但语域和搭配不同：provide 最中性通用，offer 强调主动提出、对方可选择接受或拒绝，render 语气正式生硬、常与抽象名词连用，supply 强调持续或大批量供应。这里不比较 render 作“渲染（图像）”或“使变得（某状态）”、offer 作“提出（建议）”等其他义项。

Compared meaning: to ask someone to marry you (verb).

比较义项：向某人求婚（动词）。

• offer 本词

  Formal and somewhat old-fashioned; needs an explicit object, usually the fixed phrase 'offer marriage' or 'offer someone one's hand' — the word 'marriage' cannot be dropped the way it can with propose.

  语气正式、略显过时；通常需要明确的宾语，常用固定搭配 offer marriage 或 offer someone one's hand（正式求婚），不能像 propose 那样省略 marriage 一词。

  In the letter, he formally offered her marriage, as custom required.

  按照当时的习俗，他在信中正式向她求婚。

• propose

  The everyday, standard verb for asking someone to marry you; often used alone as 'propose to somebody', with the marriage proposal understood without stating it.

  求婚的常用、标准说法；常单独用作 propose to somebody（向某人求婚），求婚的内容可以不必明说。

  He got down on one knee and proposed to her in the park.

  他单膝跪地，在公园里向她求婚了。

Both words can mean to ask someone to marry you. Propose is the everyday, standard verb, often used alone as 'propose to somebody', with the marriage proposal understood. Offer is formal and old-fashioned, needing an explicit object, usually the fixed phrase 'offer marriage'.

propose 和 offer 都可以表示向某人求婚，但语气和用法不同：propose 是现代英语中最自然、最常用的说法，甚至可以单独说 propose to somebody（求婚的内容可以省略）；offer 语域更正式、略显过时，通常要跟明确的宾语，固定搭配是 offer marriage 或 offer someone one's hand。这里不比较 offer 的“提供、提出”义（如 offer a training program）和 propose 的“提议、建议”义（如 propose a new schedule）。
