**Option 2: Slightly More Informative**

**Option 3: Emphasizing the Educative Aspect**

**Which one to choose depends on your specific blog and content:**

* If you mainly want to be helpful to searchers, Option 1 is sufficient.
* If you want to clarify what the post tag is about on your site, Option 2 is good.
* If you are trying to attract people interested in the history of the language, Option 3 is best.
* If you are trying to say “The stuff in this tag is about the etymology in this blog post series,” then option 4 is perfect.
