Here are a few options for the description of the WordPress post_tag “學名” (xué míng – Scientific Name) in Traditional Chinese, catering to different levels of helpfulness and context:

**Option 1: Concise and Informative**

> 包含植物、動物或其他生物的科學名稱。了解正式的生物學術語，以及命名與分類的原則。
>
> *Translation: Includes the scientific names of plants, animals, or other organisms. Understand the formal biological terminology, and the principles of naming and classification.*

**Option 2: Slightly More Detailed**

> 標籤：學名。此標籤用於標記文章，涉及生物的正式科學名稱。學名通常是拉丁語或拉丁化的，由兩個部分組成：屬名和種名。例如，人類的學名是 *Homo sapiens*。
>
> *Translation: Tag: Scientific Name. This tag is used to mark articles that involve the formal scientific names of organisms. Scientific names are usually Latin or Latinized, consisting of two parts: the genus name and the species name. For example, the scientific name for humans is *Homo sapiens*.*

**Option 3: Focused on Usage (If the blog is about natural sciences)**

> 探索植物、動物或微生物的學名世界！ 這個標籤專注於物種的科學命名法，幫助您了解更精確的生物分類和研究。

**Option 4: Short and Sweet (If space is limited)**

> 生物的科學名稱，例如植物學名、動物學名等。
>

**Key things to consider when choosing:**

* **Your blog’s audience:** Are they beginners or more advanced readers?
* **The focus of your posts:** Are you focusing on botany, zoology, or a broader range of topics?
* **Length limitations:** WordPress might have a character limit for tag descriptions.

Choose the description that best fits your needs! I’d recommend Option 2 or 3 for most blogs dealing with biological subjects. Good luck!
