study

Compared meaning: a school course or academic field (noun).

比较义项：学校课程或学术领域中的“科目/学科”（名词）。

• subject

  Names a specific class or topic taught in school, like History or Math; used in everyday talk about timetables, grades, and favorite classes.

  指学校或课程中的一门具体科目，比如历史或数学；常用于日常谈论课程表、成绩和喜欢的科目。

  Math was never my strongest subject in school.

  数学在学校里从来都不是我最擅长的科目。

• study 本词

  Refers to a broader academic field or discipline, often phrased as the study of X or as the plural studies; more formal, common in university contexts like linguistics or environmental studies.

  指更广泛的学科领域，常以“是……的研究”这样的说法表达，或用复数studies构成学科名称；语气更正式，常见于大学语境，例如语言学或环境研究。

  Linguistics is a fascinating study of how languages change over time.

  语言学是一门研究语言如何随时间演变的有趣学科。

Both can mean a course or field of learning, but subject is everyday: one specific class in school, like History. Study is more formal, naming a broader academic field, often as 'the study of X' or the plural 'studies,' as in linguistics or environmental studies.

这两个词在“科目、学科”这一意思上很接近，但subject更日常，指学校课程表里的一门具体科目；study更正式，指一个学术研究领域，常以“the study of X”这样的说法或构成“studies”学科名来表达。这里不比较subject表示语法中的“主语”或“臣民”的意思，也不比较study作动词“学习”或作名词“研究报告”的意思。
