sort

Compared meaning: a type or category (noun).

比较义项：种类（名词）。

• kind

  More neutral and slightly more formal than sort; used for plain, straightforward classification without suggesting doubt about the category.

  比 sort 更中性、语气也略正式；常用于直接、明确的分类，不带任何怀疑或含糊的意味。

  Please tell me what kind of allergy you have so the doctor can help.

  请告诉我你有哪种过敏，这样医生才能提供帮助。

• sort 本词

  More informal, especially in British English; often appears in 'some sort of' to hint at uncertainty or mild suspicion about the category.

  语气更随意，尤其在英式英语中；常出现在“某种”（some sort of）这样的表达里，暗示对类别的不确定或轻微怀疑。

  That email sounds like some sort of scam, so don't click the link.

  这封邮件听起来像是某种诈骗，所以不要点击链接。

Kind and sort both mean a type or category, often used interchangeably. Kind is neutral, for plain, clear classification. Sort is more informal, especially in British English, often in 'some sort of' to show doubt about the category. This does not cover kind meaning 'friendly'.

这两个词在“种类”这一意义上非常接近，多数情况下可以互换；但 sort 语气更随意，常出现在“某种”（some sort of）这类表达中，暗示对类别的不确定或怀疑，而 kind 更中性、用于直接明确的分类。这里不比较 kind 表示“友善的”这一形容词义项。

Compared meaning: to group things into categories (verb).

比较义项：把事物分门归类（动词）。

• sort 本词

  A common, everyday verb; can mean grouping items OR simply putting them in order. Used for casual, physical tasks and often paired with "into" or "by".

  日常通用词；既可以指把物品分组，也可以只表示排出顺序。常用于日常、具体的事务，常与“into”或“by”搭配。

  Can you sort the laundry into darks and lights before washing?

  你能在洗衣服之前把衣物分成深色和浅色两堆吗？

• classify

  A more formal, technical verb; always implies grouping by shared type, category, or quality according to a system, common in scientific or official contexts.

  更正式、专业的动词；总是指依据类型、类别或性质进行系统性分组，常见于科学或官方语境。

  Biologists classify whales as mammals, not fish.

  生物学家把鲸鱼归类为哺乳动物，而不是鱼类。

Sort and classify both mean to separate things by a standard, but differ. Sort is common and everyday, meaning to group items or simply put them in order. Classify is more formal, always meaning grouping by shared type or quality, common in scientific contexts.

两者都指把事物按某种标准分开归类，但 sort 更口语化，也可以只表示排出顺序，不一定依据类别；classify 更正式，强调依照类型或性质进行系统分类，常见于科学、官方语境。
