Meaning and Usage
The suffix ～部 (～ぶ) is commonly used to indicate a 'part' or 'section' of something, such as a book, organization, or group. It can refer to a department within a company (e.g., 営業部 sales department), a section of a document or book (e.g., 第3部 third part), or a club/section in a school or community (e.g., 体育部 sports club).
Common Collocations
- 営業部 (えいぎょうぶ): sales department, used in business contexts.
- 第～部 (だい～ぶ): the ~th part/section, used for books, reports, or presentations.

Register and Nuance
～部 is a formal and neutral suffix often used in written and spoken Japanese when referring to organizational units or divisions. It is not casual and is appropriate in business, academic, and official contexts.
Learner Tips
A common confusion is mixing ～部 with ～課 (か), which also means department but usually refers to a smaller unit within a 部. Remember that ～部 is a broader division, while ～課 is a subsection. Also, ～部 can refer to parts of a book or document, so context is important to understand the meaning.
