Okay, here’s a description for a WordPress post tag with the title “主題句” (Traditional Chinese for “Subject Sentence” or “Topic Sentence”):

**Description: (Choose ONE or a combination that best fits the target content)**

* **中文:** 涵蓋文章主要觀點、核心思路、或關鍵陳述的標籤。用於快速識別文章的重點資訊。 (This means: A tag encompassing the main point, core idea, or key statement of an article. Used for quickly identifying the key information.)

* **中文 (更详细):** 標記文章中的主題句，即通常位於段落開頭或結尾，概述該段落內容的重要句子。方便讀者理解文章結構和主要論點。 (Marking the topic sentence in the article, usually at the beginning or end of a paragraph, summarizes the important sentences summarized of the paragraphs. Enabling readers to understand the structure of the article and main arguments.)

* **English Translation (if applicable):** Subject Sentence
(Consider using this especially if you want to target a wider audience using a bilingual site but this should not be the entire description.)

* **中文 (簡單):** 文章中心句，通常呈現段落的核心概念。 (Core sentence of the article, usually presenting the central concept of the paragraph.)

**Tips for Choosing/Using the Description:**

* **Target Audience:** Consider who will be reading your content. If it’s primarily Chinese speakers, use the descriptions in Chinese. If it’s a bilingual website, include the English translation.
* **Content Focus:** The description should reflect the type of content you’ll be tagging. Are you focusing on identifying topic sentences within paragraphs? On quickly summarizing articles? Choose the description that best clarifies the purpose of this tag.
* **Brevity & Clarity:** Keep the description concise and easy to understand.
* **SEO (Optional):** You could subtly incorporate relevant keywords related to your blog’s topic (e.g., “中文寫作”, “英文寫作”, “文章分析” – depending on the content) while maintaining natural language.

**How to Input this into WordPress (in the Tag Edit Screen, typically):**

1. You’ll find the “Description” field in the WordPress admin area when you’re creating or editing a post tag.
2. Enter the chosen description into the textbox.
3. Click “Update” or “Save.”

**Example Usage in Context:**

Let’s say you’re writing a blog post about analyzing essay structure. After creating the tag “主題句,” then the description selected from the above will be populated. When you are writing the essay and encounter the topic sentence, you can then include the tag “主題句”. This would help your readers understand the main arguments and concepts in an organized and efficient manner.
