Meaning and Usage
The character 序 (xù) primarily refers to 'order' or 'sequence' in a general sense, such as the order of events, numbers, or actions. It is also used to mean 'preface' or 'introduction' in books or speeches.
Common Contexts
- Order/Sequence: 序号 (sequence number), 排序 (to arrange in order), 发言顺序 (speaking order).
- Preface/Introduction: 序言 (preface), 书的序 (book's introduction).
Collocations and Patterns
- 序号 (xùhào): sequence number, used in lists or queues.

Usage Notes
When using 序 to indicate order, it often appears in formal or written contexts rather than casual speech. For example, in daily conversation, people might say 排队 (line up) without explicitly mentioning 序. In literary or official contexts, 序 is common to denote structured order or the introductory part of a text.
Avoid confusing 序 with 排 (pái), which also means to arrange or line up but is more action-oriented. 序 emphasizes the concept of order or sequence itself.
Summary
Use 序 when referring to the concept of order, sequence, or the introductory section of a text. It is a formal term often found in writing, official documents, and structured settings.
