What's the difference between post and posts, tag and tags?

What's the difference between "post" and "posts", tag and tags?

I find this to be strange looking at the templates.

Why does the plural form exist for those two, and not for others. I don't see a template for "author" or "comment".

Hi desbest and welcome to PW!

The plural version is the parent template and the singular is the template for the child pages which contain the actual posts and tags. This allows different rules for the parent and child templates. It allows you to say that any children of the tags page must use the tag template.

Look at the page tree for Tags:

Tags (tags template)

    CSS (tag template)

    Customization (tag template)

    Photography (tag template)

    Templates (tag template)

    Uninteresting (tag template)

    Videos

 

This also allows for creation of a Tags PageField that allows for selecting these tags on other pages (eg from a post).

 

It's all about structuring the content and defining what is allowed to be used where.

 

Here is a great tutorial from kongondo about page structuring:
