Here are a few options for a WordPress post tag description for “單獨” (dān dú) in Traditional Chinese, ranging in tone and focus:

**Option 1 (Concise & Practical):**

> Tags posts related to independence, being alone, separation, or individual occurrences. 使用這個標籤標記與獨立、獨處、分離或個人事件相關的文章。

* **Why this works:** Direct to the point, covers common meanings of 單獨, and includes a translation for global users.

**Option 2 (More Nuanced):**

> Articles tagged with “單獨” explore themes of solitude, isolation, being on one’s own, or specific instances of standalone actions or entities. 探討孤獨、隔絕、獨自一人，或獨立行動與個體的文章都會使用這個標籤。

* **Why this works:** Uses slightly more sophisticated vocabulary to broaden the scope and adds context.

**Option 3 (Focus on Context):**

> This tag, “單獨”, categorizes posts where the idea of being separate, distinct, or individual is central to the content. Think of it as “being on your own,” “being alone,” or “being unique.” “單獨” 標籤用於分類以分離、獨立、獨特性為主旨的文章。可以理解為「獨自一人」、「孤身」或「獨特」。

* **Why this works:** Offers relatable English examples alongside the Chinese term and provides clarity on the tag’s core concept.

**Option 4 (Short and Sweet):**

> For posts about being alone or separate. 用於討論獨處或分離的文章。

* **Why this works:** Super simple and easily understood.

**Key Considerations when choosing:**

* **Your Niche:** Consider the topics generally covered by your blog. This will help you fine-tune the description for the most relevant uses.
* **Target Audience:** Will you be targeting a readership mainly in Taiwan, Hong Kong, or Mainland China (knowing differences in nuances for the same words), or perhaps a global audience? The descriptions provided here are generally geared towards a traditional Chinese (Taiwan/Hong Kong) audience but easily understandable.
* **Overall Tone:** Match the tag description to the voice and style of your blog. If you are informal, choose the very basic description. If you are more academic, something more nuanced would be appropriate.
* **Keyword Density & Search Optimization (SEO):** While not the primarily focus of a tag description, consider if you are using the word “單獨” and related synonyms in your post and page titles, meta descriptions and content within the posts themselves to strengthen SEO.

Choose the description that best suits your needs. Remember to save it inside of the appropriate WordPress tag setting!
