Here are a few options for descriptions for a WordPress post tag titled “無法使用” (Wúfǎ Shǐyòng), catering to different purposes:

**Option 1: Concise & Direct (Best for general use)**

* **Description:** 標記無法正常運作的功能、項目或問題。 (Bāo jì bù néng zhèngcháng yùnzuò de gōngnéng, xiàngmù huò wèntí.) – Marks features, items, or problems that are not working correctly.

**Option 2: More Explanatory (Useful for Support-related tags)**

* **Description:** 帖子標籤，用於描述系統、軟體或程式碼中遇到的無法使用的問題。 (Tiězi biāoqiān, yòngyú miáoshù xìtǒng, ruǎnjiàn huò chéngxù mǎ zhōng yùdào de wúfǎ shǐyòng de wèntí.) – Post tag used to describe issues encountered within a system, software, or code that cannot be used.

**Option 3: Suitable for a broader audience (e.g., user-friendly blog)**

* **Description:** 這標籤代表了在文章中提到的任何無法正常使用、出現錯誤、或是不工作的部分。 (Zhè biāoqiān dàibiǎo le zài wénzhāng zhōng tídào de rènhé wúfǎ zhèngcháng shǐyòng, chūxiàn cuòwù, huò shì bù gōngzuò de bùfèn.) – This tag represents any part mentioned in the article that is not working correctly, is experiencing errors, or is not functioning.

**Option 4: Emphasizing Broken Functionality**

* **Description:** 用於標記失效、損壞、或不再可用功能的文章。 (Yòngyú biāo jì shīxiào, sǔnhuài, huò bù zài kěyòng gōngnéng de wénzhāng) – For articles that mark features that are broken, corrupted or no longer available for use.

**Key Considerations when Choosing:**

* **Target Audience:** Who will be reading your blog/website? Choose the description that makes the most sense to them.
* **Blog Content:** What will the tagged posts be *about*? Reflect that topic in the description.
* **SEO:** While not a huge issue for tag descriptions, including relevant keywords can help. “問題” (problem), “錯誤” (error), or “功能” (feature) might be useful if appropriate.
* **Brevity:** WordPress typically displays the description somewhere. Shorter is generally better.
* **Clarity:** The goal is to explain the meaning of the tag to both users and search engines.
