  Category highlights a group defined by shared characteristics within a classification system, commonly used for sorting items, genres, or entries, as in a product or complaint category.

  category强调在分类体系中按共同特征归类的群体，常用于对物品、体裁或条目进行分类，例如产品类别或投诉类别。

• class

  Class often denotes a type or grade within a technical, scientific, or hierarchical classification, such as a class of drugs or vehicles, and can carry a sense of rank or quality.

  class常指技术性、科学性或带等级意味的分类中的一种类型或等级，例如药物类别或车辆类别，有时还带有等级或品质的含义。

  Insulin belongs to a class of drugs called hormones.

  胰岛素属于一类被称为激素的药物。

Category and class both mean a group of things with shared features. Category stresses fitting something into a classification system, often for sorting items. Class is more common in technical or scientific classification, like a class of drugs, and can carry a sense of rank.

这两个词表示“种类”时意思相近，但category强调按共同特征归入某个分类体系，常用于对物品、体裁或条目进行分类；class则更常见于技术性、科学性或带等级意味的分类，如药物类别或车辆类别。这里不比较class的“班级”（学生群体）或“社会阶层”等含义。
