Pro Tip

Distinguish from 课本

教科书 is a broader term that includes 课本 (textbook for a specific course) but may also refer to reference books or educational materials. 课本 specifically refers to the main textbook used for a course.

Gold Rule

Formal vs. Informal

Use 教科书 in formal contexts such as education, academic discussions, or when referring to official educational materials. Avoid using it in casual conversations.

Word Origin

教科书 is composed of 教 (jiào, 'teach'), 科 (kē, 'subject' or 'branch of study'), and 书 (shū, 'book'). The term emerged in modern Chinese to describe standardized educational books.

Usage Notes

教科书 is commonly used in educational contexts and is not typically used metaphorically. It is a formal term and is not slang or idiomatic.
